Distributive property
3(x+3)
3*x + 3*3
3x+9
divide by three to simplify
x + 3
if you’re supposed to solve it, subtract three
x = -3
Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years
Option A is the correct method to find the age of Peter and Winnie.
9 to the 3rd power is 729
And 2 to the 5th power is 32. You multiple 9, 3 times. 9 times 9 times 9 and you multiply 2, five times. 2 times 2 times 2 times 2 times 2
