A restaurant sells a coffee refill mug for $6. Each refill costs $2. Last month Keith spent $30 on a mug and refills. Write an equation
you can use to find the number of refills Keith bought. Use x for
your variable and do NOT type and spaces. *

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

what is the question here

step-by-step explanation:

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
