Angle A and B have a sum of 187º. Angle A is 12 more than 3
times a number, angle B is 7
more than 5 times the same
number. What is the measure of
angle A and angle B?

let no. be x

A= 12+ 3x

B= 7+5x

A+B=187

12+7+3x+5x=187

x=21

therefore, A=75°

B=112°

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
