For any two integers x and y, |x + y| = |x| + |y|. _ is this true or false if false provide counterclaim

False.

Let x = -1 and y = 1. Then x + y = 0, so that

|x + y| = |0| = 0

but

|x| = |-1| = 1

|y| = |1| = 1

|x| + |y| = 1 + 1 = 2

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
