Evaluate 15-0.75w+8x when w=12 and x=1/2

Put the values of w = 12 and x = 1/2 to the expression 15 - 0.75w + 8x.

15 - 0.75(12) + 8(1/2) = 15 - 9 + 4 = 6 + 4 = 10

+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
