Answer: 12

Step-by-step explanation:

this is a right angled triangle so you use the pythagorean theory

which is a^2 + b^2 = c^2

you have c and b already. c is the hypotenuse.

a^2 + 16^2 = 20^2

a^2 + 256 = 400

a^2 = 400 - 256

a^2 = 144

then you square root 144 and get..

a = 12

Answer:

50 combos

Step-by-step explanation:

Put it into an equation first in order to find x.

2x + 250 = 7x

Subtract 2x from both sides.

250 = 5x

Then divide both sides by 5.

x = 50

Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.

You can check your work by plugging in the number to both.

$250 plus the $2 times 50 combo meals.

250 + 2(50) = 350

$7 times 50 combo meals

7 x 300 = 350
