3(2x + 7) = 9 ...divide both sides by 3
2x + 7 = 9/3
2x + 7 = 3
2x = 3 - 7
2x = -4
x = -4/2
x = -2
or this way..
3(2x + 7) = 9
6x + 21 = 9
6x = 9 - 21
6x = - 12
x = -12/6
x = -2
Answer:
im passing this concept trust me the anser is airplane B
Step-by-step explanation:
Raymar ate 1/4. That leaves 3/4 left. Kalen ate 1/4 of the 3/4 left. We need to find how much 1/4 of 3/4 is, so we have to divide 3 by 4. To make this easier to solve, we need to change the form of the fractions to make it in sixteenths instead of fourths. So Raymar ate 4/16 leaving 12/16 left and Kalen ate 1/4 of the 12/16 left.This means we can divide 12 by 4 and get 3. Kalen ate 3/16 of the entire pan. Or just draw a diagram similar to this.
