What properties were used to prove that the expressions 7x + 4 - x - 2 and 6x + 2 are equivalent
Answers
Answer:
they are equivalent
Step-by-step explanation:
for 7x+4-x-2, combine the like terms first. Do 7x-x (x by itself is the same thing as 1x) to get 6x. Then, do 4-2 to get 2. You get 6x+2, which is equivalent to 6x+2.
Answer:
I THINK the answer is distributive, associative, and commutative
Step-by-step explanation:
The equation, 7x+4-x-2, is distributive proporty.
The equation, 7x-x+4-2 is commutative
The equation, ( 7-1 ) x+4-2 is distributive

To create the flower gardens, Wendell bought six pieces of wood. Pieces A and B are 6 feet long, pieces C and D are 8 feet long, piece E is 3 feet long, and piece F is 2 feet long.
Answers
Answer:
Part B: They cannot make a triangular garden because in order for 3 sides to make up a triangle, 2 sides when added up have to be greater than the other side. For example, side D + E has to be greater than side F. If it was a triangle, side E + F has to be greater than side D. Since 2 + 3 < 8, this cannot be a triangle.
Step-by-step explanation:
Part C: They can make a rectangle because they can use pieces A and B for the length and pieces C and D for the width.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
A local animal rescue has 20 people that help foster pets while they are
waiting on finding their homes. They expect to gain two additional people
willing to foster animals each month. The amount of animals in need of
homes in the community is currently 10 and growing at a rate of 15% per
month. When will the amount of homeless pets surpass the amount of foster
homes available?
A) Write the two functions that represent this situation.
B) Create a table of values for x=0 to x=13.
C) Approximate the solution(s). Why is this the approximate solution?
D) Using graph paper (and the table of values), sketch the situation to
show the exact solution.
Answers
Answer:
A) Let f(x) represent the number of foster homes available after x months, and let g(x) represent the number of homeless pets after x months.
f(x) = 20 + 2x (since 2 additional people are expected to foster each month)
g(x) = 10(1.15)^x (since the number of homeless pets is growing at a rate of 15% per month)

Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)
Answers
The total Weight blocks maria has is 15.2 pounds.
What is Fraction?A fraction represents a part of a whole.
Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.
Each full block weight \(3\frac{8}{9}\) pounds
We need to find the Weight blocks maria has
Let us convert the mixed faction to improper fraction
35/9 = \(3\frac{8}{9}\)
As there are 4 full cement, blocks
So multiply 4 with \(3\frac{8}{9}\)
4×35/9
4×3.8
15.2
Hence, the total Weight blocks maria has is 15.2 pounds.

How many times does 15 go int 135? who ever gets it right gets 500 points
Answers
Answer:
9 times
Step-by-step explanation:
The number 15 multiplied to the number 9 which gives the value 135.
To find the that how many 15 is to get 135, division should be performed.
So, dividing 135 by 15 gives:
= 135 ÷ 15
15 | 135 | 9
135

0
Thus, the quotient is 9.
Therefore, 15 goes into 135 exactly 9 times.

Answers
Answers for pictures 1, 2, &3
Question 1: P = 35 degrees
It is given to us that angles N and P are complementary.
Complementary angles means the sum of the angles = 90 degrees.
Because angles N and M are supplementary, meaning they = 180 degrees, you can subtract angle M from 180.
180 - M = N
180 - 125 = 55
N = 55 degrees
Now that we know N = 55 degrees, we subtract that from 90 degrees to find P for N + P = 90 degrees, so if we subtract 55 from 90 we will get the value of angle P.
90 - N = P
90 - 55 = 35
P = 35 degrees!
Question 2: Option 4
We are trying to figure out which angles are congruent to one another.
We can rule out option one, for angles 1 & 4 are supplementary meaning their sum = 180 degrees.
The same applies for options 2 & 3, leaving us with the correct answer, option 4. We can make sure this is true because angles 3 & 5 are alternate interior angles, and alternate interior angles of parallel lines are congruent.
Question 3: x = 5
The three different angles add up to 180 because they are a straight angle.
First, we need to find out what 9 and 10 are equal to.
To do so, we can subtract 85 from 180.
180 - 85 = 9x + 10x
9x + 10x = 95
Now that we have an equation, we can simplify to find the value of x.
9x + 10 = 95
19x = 95
Divide by 19 on each side to isolate the variable x
x = 5

The sum of the number in each of the four rows is the same The sum of the numbers in each of the three columns is the sameThe sum of any row does not equal the sum of any column\(\bold{\underline{ Let's \: Begin}}\)
According to the Second rule :-
\(\sf{ 75+b+83=76+80+d=a+81+85+78+c+e }\)
\(\sf{ 158 + b = 156 + d = 166 + a = 78 + c + e ...(1)}\)
According to the first rule :-
\(\sf{ 75+76+a+78 = b+80+81+c = 83+86+d+e}\)
\(\sf{ 229 + a = 161 + b + c = 168 + d + e ...(2)}\)
From ( 1 ) we got :-
\(\sf{ 158 + b = 166 + a, 156 + d = 166 + a }\)
\(\sf{ b = 166 - 158 + a, d = 166 - 156 + a }\)
\(\sf{ b = 8 + a, d = 10 + a ...(3)}\)
Subsitute (3) in ( 2 ) :-
\(\sf{229+a = 161+8+a+c = 168+10+a+e}\)
\(\sf{ 229+a = 169+a+c = 178+a+e}\)
We can write it as :-
\(\sf{ 229+a = 169+a+c \:or\:229+a = 178+a+e}\)
\(\sf{ c = 299-169+a-a\:or\:e = 229-178+a-a}\)
\(\sf{ c = 60 \: and \: e = 51 }\)
Subsitute the value of c and e in ( 1 ):-
\(\sf{ 158 + b = 156 + d = 166 + a = 78 + 60 + 51 }\)
\(\sf{ 158 + b = 156 + d = 166 + a = 189}\)
Now,
\(\sf{ For \: b, 158 + b = 189 }\)
\(\sf{ b = 189 - 158 }\)
\(\sf{ b = 31}\)
\(\sf{ For \: d , 156 + b = 189 }\)
\(\sf{ d = 189 - 156 }\)
\(\sf{ d = 33}\)
\(\sf{ For \: a, 166 + a = 189 }\)
\(\sf{ a = 189 - 166 }\)
\(\sf{ a = 23 }\)
Hence, The value of a, b, c, d and e is 23, 31 ,60 ,33 and 51 .

A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

A carnival has a duck-pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 62 ducks floating in the pond. There are 7 ducks marked as large-prize winners, 12 ducks marked as medium-prize winners, and 24 ducks marked as small-prize winners. Find the theoretical probability of winning a small prize at the duck pond. Express your answer as a percent. If necessary, round your answer to the nearest whole.
Answers
Answer: 39%
Step-by-step explanation: The probability of winning a small prize is the number of small-prize ducks divided by the total number of ducks:P(small prize) = 24 small prize ducks / 62 total ducksTo express this as a percent, we multiply by 100:P(small prize) * 100 = (24 / 62) * 100 = 38.71%Rounding to the nearest whole, the theoretical probability of winning a small prize at the duck pond is 39%.
