Answer 2

Answer: The easiest way to find an equivalent ratio is simply by timesing one number by something, and then timesing the other number by the same one.

For example:
5 X 2 = 10.
6 X 2 = 12.
5:2 = 10:12.

5 X 3 = 15.
6 X 3 = 18.
5:2 = 15:18.

Hope this helps :)

b. 5+3 = 3+5
c. (5)(1+2) = (5)(1) + (5)(2)
d. 15=15

Answers

1) Ratio - 4:1

thus, 4x + 1x = 20
5x = 20

thus, x = 20/5 = 4

thus, x = 4
and, 4x = 16

Thus, the answer is (C) 16 boys and 4 girls

2) According to distributivity, a(b+c) = ab + ac

Thus, the answer is (C)

1.4x+x=20
5x=20
x=4 there are 16 girls and 4 boys

What’s a multi step equation that equals 22, 23, 29? please this is urgent

Answers

These are three examples of multi-step equations that yield the respective values of 22, 23, and 29.

Here are three multi-step equations that equal 22, 23, and 29, respectively:

Equation equaling 22:

3x + 4 = 22

Solution:

3x = 22 - 4

3x = 18

x = 18 / 3

x = 6

So, the equation 3x + 4 = 22 has a solution of x = 6, which satisfies the condition.

Equation equaling 23:

2x + 5 = 23

Solution:

2x = 23 - 5

2x = 18

x = 18 / 2

x = 9

So, the equation 2x + 5 = 23 has a solution of x = 9, which satisfies the condition.

Equation equaling 29:

4x - 3 = 29

Solution:

4x = 29 + 3

4x = 32

x = 32 / 4

x = 8

So, the equation 4x - 3 = 29 has a solution of x = 8, which satisfies the condition.

These are three examples of multi-step equations that yield the respective values of 22, 23, and 29.
