William gave 4 football cards to each of the 6 friends. suppose he had 54 cards left. write and solve an equation to find how many cards each friend a initially had.

+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

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
