Find the value of x.
picture below

All angles in a triangle add up to 180 degrees. Make all the angles in this triangle add up to 180 in an equation to solve for x.

(4x + 7) + (11x - 9) + 32 = 180

Combine like terms. (4x + 11x) and (7 - 9 + 32)

15x + 30 = 180

Subtract 30 from both sides.

15x = 150

Divide both sides by 15.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

ratio is 2 : 9

the answer is three

13.5 : 3
