Answer:
G(2b) = 10b + 3
Step-by-step explanation:
To find G(2b), simply plug in 2b wherever there is an x in G(x).
G(x) = 5x + 3
G(2b) = 5(2b) + 3
G(2b) = 10b + 3

Answer:
80
Step-by-step explanation:
So, let's say the total number of pizzas is x
If 15% of x, the total, is 12, then x * 0.15 must = 12
Use this to make an equation
12 = 0.15x
Divide both sides by 0.15 to get x on its own
12 / 0.15 = x0.15 / 0.15
80 = x
80 pizzas were sold
Answer:
A. I and IV
Step-by-step explanation:
I. 4(6 - x)
II. 4 + (6 - x)
III. 6(4 - x)
IV. (6 - x) + (6 - x) + (6 - x) + (6 - x)
Let's keep them in the simplest expressions.
I. 4(6 - x)
4(6) - 4x
24 - 4x
II. 4 + (6 - x)
4 + 6 - x
10 - x
III. 6(4 - x)
6(4) - 6x
24 - 6x
IV. (6 - x) + (6 - x) + (6 - x) + (6 - x)
6 - x + 6 - x + 6 - x + 6 - x
6 + 6 + 6 + 6 - x - x - x - x
24 - 4x
Only I and IV have the same result.
