Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is \(\displaystyle{8+x}\) years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of \(\displaystyle{x+8+x=62}\) (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

\(\displaystyle{2x+8=62}\)

Step 4: Subtract both sides by 8

\(\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}\)

Step 5: Divide both sides by 2

\(\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}\)

Since Jiri’s age is defined as \(x\) years old. Therefore, Jiri’s age is 27 years old.

Answer:

62/3 or 20.7(1dp)

Step-by-step explanation:

2 2/3 = 8/3

7 3/4 = 31/4

so 31/4 * 8/3 = 62/3

As a whole number the answer  is 20.7(1dp)

Answer:

Step-by-step explanation:

Answer:

A. 9 x 3^0 = 9 x 1 = 9

B. the value doesnt vary depending on y as any number whose power is zero is always 1.

Step-by-step explanation:

(2/3)(-4)(9) = -24

(5/16)(-2)(-4)(-4/5)= -2

(-3/4)(7/8)=-21/32

(2 3/5) (7/9)=91/45

Answer:

A

Step-by-step explanation:

It shows 120 for both the sides of the angle, which makes it parallel.

B is wrong because they don't have the same angle measure.

C is wrong because they don't have the same angle measure.

D is also wrong, because it shows both the measures of angle A, and you don't know what angle B is.

Answer:

The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.

Step-by-step explanation:

If we say \(x\) is the first number, then the next consecutive number will be \(x+1\).

Using this, we can make an equation.

\(x+(x+1)=55\)

\(2x+1=55\)

\(2x=54\)

\(x=27\)

And so we know that the two consecutive numbers are 27 and 28.

Hope this helps.

Answer: x=108 degrees

Step-by-step explanation:

Since ST is a straight line, it measures 180 degrees.

This means that

x+(2/3)x=18

The simplified version is 5x/3=180. Now, we multiply both sides by 3. The equation becomes 5x=540 you would divide 5 by both sides which is ultimately x=108.

Answer:

x=108 degrees

Step-by-step explanation:

We know that since ST is a line, it equals a total of 180 degrees.

Let's write an equation:

\(180=x+\frac{2}{3}x\)

simplify

\(180=\frac{5}{3} x\)

divide both sides by 5/3

108=x

So, x=108 degrees.

Hope this helps! :)

Answer:

A) 18

B) 48 , 60 and 72

Step-by-step explanation:

A) since the angles are in ratio 2:4:4 there is a constant proportionality that we call k. So the angles can be represented by 2k,4k and 4k. That means 2k + 4k + 4k = 180. K=18

B) The angles would add up to 180 as a general rule, make x the multiplier and

4x+5x+6x=180

15x=180

X=12

Then

4(12)=5(12)+6(12)=180

48, 60 and 72

Answer:

f = 5/4

Step-by-step explanation:

f/2 = 5/8

Multiply both sides by 2.

f = 10/8 = 5/4

Answer:

f=1.25

Step-by-step explanation:

f/2=5/8

To get 8, you must multiply 2 by 4.

So

You must do the same to the numerators -

4 times x = 5

5/4=1.25

Answer: 26

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.

Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

Hope this helps.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

A/m=-2. since x goes up by 2 on the table, y decreases by 4 on the table, but if the next part of x on the table was 6, then y would be -2.

Answer:

c. 2/13

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.

Answer:

I believe Claire makes $24.50 and Brooklyn makes $14.50, so if you wanted to make Brooklyn walk an extra hour, she would have 24.00 adding the supply fee which is $5 which would make it $29.00.

8.50x15=127.5

9.50x5=47.5

9.50x13=123.5
