Answer: a = 26, b = 24
Step-by-step explanation:
a + b = 50
a - b = 2
If we sum them, we got 2a = 52, so a = 26
Substitute to either one of the equations: 26 - b = 2, so b = 24
Answer:
Step-by-step explanation:
Let one number be x and the other number be y
x + y = 50
x - y = 2
We can get the value of one of the numbers from either of the 2 equations.
x = 2 + y (by transposing)
So, we can substitute the value of x in the first equation
x + y = 50
2 + y + y = 50
2 + 2y = 50
2y = 50 - 2
2y = 48
y = 48/2
y = 24
24 + x = 50
x = 50 - 24
x = 26
For verification :-
x- y = 2
26 - 24 = 2
2 = 2
LHS = RHS
So, the 2 numbers are 26 and 24.

What is transformation?A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure.
Given that, parallel lines l, m, and n are shown. If line l is mapped to line m and line m is mapped to line n,
We can see line is the original line is l which is first mapped into line m then into line n, so, we can say line is mapped to n.

A bag of 10 Marbles has the following composition:
Red – 3
Green – 4
Blue – 2
Yellow – 1
What is the Simple Probability of reaching in and extracting a Yellow marble?
Answer: So, the simple probability of reaching in and extracting a yellow marble from the bag is 0.1 or 10%.
Step-by-step explanation: To calculate the simple probability of reaching in and extracting a yellow marble from the bag, we need to divide the number of yellow marbles by the total number of marbles in the bag.
The bag contains a total of 10 marbles, and there is only 1 yellow marble. Therefore, the probability of extracting a yellow marble can be calculated as:
Probability = Number of Yellow Marbles / Total Number of Marbles
Probability = 1 / 10
Simplifying this fraction gives us:
Probability = 0.1 or 10%

What postulate or theorem allows you to state that angle DEF is congruent to angle GHJ
Then you can state that angle DEF is congruent to angle GHJ.
The postulate or theorem that allows you to state that angle DEF is congruent to angle GHJ is the Angle-Angle (AA) Postulate.
This postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the third pair of angles must also be congruent.
In this case, if you have two triangles, one with angles DEF and the other with angles GHJ, and
you know that angle D is congruent to angle G and angle E is congruent to angle H, then by the AA Postulate, you can conclude that angle F is congruent to angle J.

Refer to the table summarizing service times (seconds) of dinners at a fast food restaurant. How many individuals are included in the summary? Is it possible to identify the exact values of all of the original service times?
Time (sec) Frequency
60 to 119 7
120 to 179 24
180 to 239 14
240 to 299 1
300 to 359 4
Answer:
Based on the provided information, the table summarizes service times (in seconds) of dinners at a fast food restaurant. To determine the number of individuals included in the summary, we can sum up the frequencies listed in the table:
7 + 24 + 14 + 1 + 4 = 50
Therefore, there are 50 individuals included in the summary.
Regarding the exact values of all the original service times, it is not possible to determine them precisely based on the given information. The table only provides ranges of service times and their corresponding frequencies. We can determine the range within which each individual's service time falls, but we cannot determine the exact value within that range.
This problem refers to a right triangle ABC with C= 90°. Begin each problem by drawing a picture of the triangle with both the given and asked for information labeled appropriately. Answer to the nearest hundredth of a foot. If B=37.56 and a =49.94ft then b
The side b is approximately 80.02 feet in length. In a right triangle ABC with angle C equal to 90°, if angle B is 37.56° and side a is 49.94 feet, we can solve for side b using the trigonometric function sine.
First, we can label the triangle as follows:
Side a is opposite angle A,
Side b is opposite angle B,
Side c is the hypotenuse.
Let's label the triangle with the given and asked for information. Angle C is the right angle, angle B is 37.56°, side a is 49.94 feet, and side b is the side we are trying to find.
Using the sine function, we have:
sin(B) = opposite/hypotenuse
sin(37.56°) = a/b
Now we can substitute the known values:
sin(37.56°) = 49.94/b
To solve for b, we rearrange the equation:
b = 49.94 / sin(37.56°)
Using a calculator, we find:
b ≈ 80.02 feet.

A parking garage in the city charges $2. 75 for the first hour and $1. 25 for each additional hour or part thereof. What is the maximum time in hours, x, that tony can park his car at the garage if he wants to pay less than $8?.
The maximum time that tony can park his car at the garage if he wants to pay less than $8 is 5.6 hours
Let's start by setting up an inequality that represents the situation:
Total cost for parking x hours <= $8
We know that the first hour costs $2.75, and each additional hour or part thereof costs $1.25. So the cost for x hours can be expressed as:
Cost = $2.75 + $1.25 × (x - 1)
Note that we subtract 1 from x because the first hour is already accounted for in the flat fee.
Now we can substitute this expression into the inequality:
$2.75 + $1.25 × (x - 1) <= $8
Simplifying this inequality, we get:
$1.25x <= $7
Dividing both sides by $1.25, we get:
x <= 5.6

A certain forest covers an area of 1900 km^2. Suppose that each year this area decreases by 4%. What will the area be after 13 years?
ANSWER
The area of the forest after 13 years is 1,11758km^2
EXPLANATION
Given that;
\(\begin{gathered} \text{ The original area of forest is 1900km}^2 \\ \text{ The percentage decrease is 4\%} \\ \text{ time is 13 years} \end{gathered}\)Follow the steps below to find the area of the forest after 13 years
Since the size of the forest decreases every year by 4%, then apply the below formula
\(\text{ A = A}_{o\text{ }}(1\text{ - r\rparen}^t\)Where
A is the area of the forest after some years
Ao is the original area of the forest
r is the interest rate
t is the time
\(\begin{gathered} \text{ A = 1900 \lparen 1 - }\frac{4}{100})^{13} \\ \\ \text{ A = 1900 \lparen1 - 0.04\rparen}^{13} \\ \text{ A = 1900 \lparen0.96\rparen}^{13} \\ \text{ A = 1900 }\times\text{ 0.5882} \\ \text{ A = 1,117.58km}^2 \end{gathered}\)Therefore, the area of the forest after 13 years is 1,11758km^2

A local museum charges $25 per adult and $12 per child for admission fees. At the end of a day, the museum made $9,014 in total admission revenue, not including sales tax, and had a total of 450 guests.
The system of equations below can be used to model the number of guests that were children, x, and the number of guests that were adults, y.
First, place a point on the graph representing the solution to the system of equations. Notice that one of the equations in the system has already been graphed.
Then, determine the approximate number of guests that were children and the approximate number of guests that were adults for that day.
The approximate number of guests that were children are 172 and adults are 278
How to determine the approximate number of guests that were children and adults for that day?From the complete question, we have the following system of equations
25x + 12y = 9014
x + y = 450
Make y the subject in x + y = 450
y = 450 -x
Substitute y = 450 - x in 25x + 12y = 9014
25x + 12(450 - x) = 9014
Expand the expression
25x + 5400 - 12x = 9014
Evaluate the like terms
13x = 3614
Divide both sides by 12
x = 278
Substitute x = 278 in y = 450 -x
y = 450 - 278
Evaluate
y = 172
Hence, the approximate number of guests that were children are 172 and adults are 278

Create a Venn diagram to illustrate each of the following: 26. (D ⋃ E) c ⋂ F
The Venn diagram for (D ⋃ E) ⋃ F will be the ovarlapped region of D,E and F.
To represent the sets D, E, and F in the Venn diagram, we first construct three overlapping circles. Then, beginning with the innermost operation and moving outward, we shade the regions corresponding to the set operations in the expression.
We shade the area where the circles for D and E overlap because the equation (D ⋃ E) denotes the union of the sets D and E. All the elements in D, E, or both are represented by this area.
The union of (D ⋃ E) with F is the next step. This indicates that we darken the area where the circle for F crosses over into the area that we shaded earlier. All the components found in sets D, E, F, or any combination of these sets are represented in this region.
The final Venn diagram should include three overlapping circles, with (D ⋃ E) ⋃ F shaded in the area where all three circles overlap.
