Soccer ball = a = 5
basketball = b = 9
volleyball = c = 7

a + b + c = 21
2a + c = 17
2b + c = 25
2a + b + c = 26

Seeing that....
a + b + c = 21
2a + b + c = 26
We can deduce that a = 5

2a + c = 17
2(5) + c = 17
10 + c = 17
Subtract 10 from both sides
c = 7

2a + b + c = 26
2(5) + b + 7 = 26
10 + b + 7 = 26
17 + b = 26
Subtract 17 from both sides
b = 9

Hope this helped!

When solving the equation, which is the best first step to begin to simplify the equation?
boyakko [2]

Answer:

<h3>Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)</h3>

Step-by-step explanation:

Given the expression

- 2 (x + 3) = - 10

The first step in solving the expression is to multiply both sides by -1/2 as shown;

-1/2(-2)(x+3) = -1/2(-10)

(x +3) = 1/2(10)

x + 3 = 5

x = 5-3

x = 2

Hence the correct option is Negative one-half (negative 2) (x + 3) = negative 10 (negative one-half)
