How do I solve for x??

The two angles given are vertical angles which mean they are the same.

x +40 = 60

Subtract 40 from both sides:

x = 20

x=20

Step-by-step explanation:

These are verticle angles, meaning the two should equal one another. If one angle is 60, its vertical angle is x+40.

x+40=60

x=20 (subtract 40 from both sides)

x= 149. 24+7=31. 180-31=149

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
