Answer:

a.) 2(x + 2) + 2 = 2(x + 3) + 1

b.) 2x + 3(x + 5) = 5(x – 3)

e.) 5(x + 4) – x = 4(x + 5) – 1

Step-by-step explanation:

a.) 2(x + 2) + 2 = 2(x + 3) + 1

0 ≠ 1

b.) 2x + 3(x + 5) = 5(x – 3)

0 ≠ -30

c.) 4(x + 3) = x + 12

x = 3

d.) 4 – (2x + 5) = (–4x – 2)

x = -½

e.) 5(x + 4) – x = 4(x + 5) – 1

0 ≠ -1

A 6 inch personal pizza has 640 calories, with 240 of those from fat. A 12 inch pizza is cutinto 8 slices. Estimate the number o

MissTica

Given:

Number calories in a 6-inch pizza = 640 calories

For the pizza of 6 inch

$A=\pi(3)^2=9\pi$

For the pizza of 12 inch

$A=\pi(6)^2=36\pi$

Number calories in a 6-inch pizza = 640 calories, therefore:

$\frac{A_{6\text{ inch}}}{A_{12\text{ inch}}}=\frac{640}{x}$

Substitute:

$\begin{gathered} \frac{9\pi}{36\pi}=\frac{640}{x} \\ Simplify \\ \frac{1}{4}=\frac{640}{x} \end{gathered}$

And solve for x:

$\begin{gathered} 1\cdot x=4\cdot640 \\ x=2560 \end{gathered}$

Now, Estimate the number of calories in one slice of a 12 inch pizza:

$\frac{2560}{8}=320$

Answer: 320 calories
