Step-by-step explanation:

Step 1: Distribute

$3(5x - 10) < 30x$

$(3 * 5x) + (3 * -10) < 30x$

$15x - 30 < 30x$

Step 2: Subtract 15x from both sides

$15x - 15x - 30 < 30x - 15x$

$-30 < 15x$

Step 3: Divide both sides by 15

$-30 / 15 < 15x / 15$

$-2 < x$

Answer: $x > -2$

Artist 52 [7]

Answer:

$478.80

Step-by-step explanation:

We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.

First of all, we will find cost of each meal with tax as:

$\text{Cost of each meal with tax}=\$12+\$12\times \frac{5}{100}$

$\text{Cost of each meal with tax}=\$12+\$12\times 0.05$

$\text{Cost of each meal with tax}=\$12+\$0.6$

$\text{Cost of each meal with tax}=\$12.6$

Now, we will find total persons at the sport banquet as:

$\text{Total persons at banquet}=15+2+21$

$\text{Total persons at banquet}=38$

To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.

$\text{Total cost of food for the banquet}=\$12.6\times 38$

$\text{Total cost of food for the banquet}=\$478.8$

Therefore, the total cost of food for the banquet is $478.80.

What’s the length of the hypotenuse in inches?

natta225 [31]

Answer:

The hypotenuse is 25 inches.

Step-by-step explanation:

This is a right triangle, so the Pythagorean Theorem applies.

I will assume you know about the Pythagorean Theorem, therefore I will not define it.

Here, I am solving for the hypotenuse.

$a^2+b^2=c^2$

$24^2+7^2=c^2$

$576+49=c^2$

$625 = c^2$

$25=c$
