Answer:

The increase is 9.1%

Step-by-step explanation:

Step 1: Make an equation

$66 * x = 72$

$66x = 72$

Step 2: Divide both sides by 66

$66x / 66 = 72 / 66$

$x = 1.09090$

Step 3: Find the increased

$1 - 1.09090$

$0.091 * 100$

9.1%

Answer: The increase is 9.1%

What is the measure of angle B in the triangle? Enter your answer in the box.

eduard

The triangle angle-sum theorem says that all those angles added together equal 180. Therefore, 120+x+x+16=180 and 2x+136=180 and 2x=44. Therefore, x = 22, which is angle B.

What is 6.974 rounded to the nearest tenth

zloy xaker [14]

6.974 rounded to the nearest tenth is 7.0, because 7 is more than 5, and since 9's there, we make that 6 to a 7.

4x + 1/3 y 2 what is the value of the expression above when x = 2 and y = 3

GenaCL600 [577]

Hoi!

To solve this, first plug in the values for x and y.

x = 2, so anywhere you see x, put 2 in its place.

y = 3, so anywhere you see y, put 3 in its place.

$4(2) + \frac{1}{2}(3)$

4 × 2 = 8

$\frac{1}{2}$ × 3 = $1 \frac{1}{2}$

$8 +1 \frac{1}{2}$ = $9 \frac{1}{2}$

$9 \frac{1}{2}$ is your answer.
