The diagram shows a shelf with braces attached across its backside. The angles made by the brace and the shelf are given as x and y. The measure of angle y is four times the measure of angel x.

Write a system of linear equations for the relationship between the measures of the angle.

Graph the two equations.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

the answer would be c:   ax + b = ax + c

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.

step-by-step explanation:

combine all like terms then its just a 2 step equation
