Answer:

115.5 tickets sold.

Step-by-step explanation:

Finding the percent of something is the same as multiplying by that percent as a decimal. So, 70% = 0.70.

0.70 x 165 = 115.5 tickets sold.

gavmur [86]

Answer:

3y = 8x + 18

for y-intercept let x = 0

3y = 8(0) + 18

3y = 18

y = 6

y-intercept is (0, 6)

THIS IS TRUE

Solving a compound inequality. check all that apply.

aev [14]

Answer:

The solutions are:

-28.25, -14.5, -2.25

Step-by-step explanation:

Given compound inequality is:

$-17.5\leq \frac{2x+4}{3}$

The compound inequalities are broken down into two inequalities to find the solution

The two inequalities will be:

$\frac{2x+4}{3} \geq -17.5$ AND $\frac{2x+4}{3}$

Solving both inequalities one by one

$\frac{2x+4}{3} \geq -17.5\\2x+4 \geq -52.5\\2x \geq -52.5-4\\2x \geq -56.5\\\frac{2x}{2} \geq \frac{-56.5}{2}\\x \geq -28.25\\\frac{2x+4}{3} < 17.5\\2x+4 < 52.5\\2x < 52.5-4\\2x \geq 48.5\\\frac{2x}{2} \geq \frac{48.5}{2}\\x < 24.25$

The solution is:

-28.25 ≤ x < 24.25

We have to see which options lie in the solution range.

The solutions are:

-28.25, -14.5, -2.25
