Answer:

x=13

Step-by-step explanation:

21=8+x

Swap sides so that all variable terms are on the left hand side.

8+x=21

Subtract 8 from both sides.

x=21−8

Subtract 8 from 21 to get 13.

x=13

if 3 half-gallon containers of ice cream on sale for $6.69,what is the price for 2 half-gallon containers?

kvv77 [185]

<h3>Answer: $4.46</h3>

===================================================

Work Shown:

3 containers = 6.69 dollars

3/3 containers = 6.69/3 dollars .... divide both sides by 3

1 container = 2.23 dollars

2*(1 container) = 2*(2.23 dollars) ... multiply both sides by 2

2 containers = 4.46 dollars

A shortcut is to start with "3 containers = 6.69 dollars" and multiply both sides by 2/3

Each mention of "container" refers to a half-gallon container.

Question:

12345 [234]

Answer:

A. Area in square inches = 1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Step-by-step explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches = 1760 square inches

B. 1 foot = 12 inches

1 inch = $\frac{1}{12}$ feet

1 square inch = $\frac{1}{144}$ feet

∴ 1760 square inches = $\frac{1760}{144}$ feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch = $\frac{1}{144}$ feet

Given f(x) and g(x) = f(x) + k, look at the graph below and determine the value of k.

Anton [14]

Answer:

Given the graph $f(x) = \frac{1}{3}x -2$ and $g(x) = \frac{1}{3}x + 3$

We have to find the value of k;

Since, g(x) = f(x) +k

$\frac{1}{3}x+3 = \frac{1}{3}x-2 +k$

Subtract $\frac{1}{3}x$ from both sides we get;

$3 = -2 +k$

Add 2 to both sides we get;

$3+2 = -2 +k +2$

Simplify:

$5 = k$

k = 5

Therefore, the value of k = 5
