Which equation can be used to solve for the value of x in the diagram? x + 40 + 115 = 180

40 + x = 115

x + 40 = 90

x = 40

Axel follows these steps to divide 40 by 9: start with 40. 1. divide by 9 and write down the remainder. 2. write a zero after the remainder. 3. repeat steps 1 and 2 until you have a remainder of zero. examine his work, and then complete the statements below.
