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.
Answer:
- 
Step-by-step explanation:
=
( cross- multiply )
6x = 5y ( divide both sides by 6 )
x =
y
Then
← substitute x =
y into the expression
= 
= 
= 
=
× - 
= - 
Answer:
Step-by-step explanation:
first of all, simplify your fraction. f(x)= -2(x+3) + 4
f(x)= (-2x-6) + 4
f(x)= -2x-2
y intercept is -2 and the slope is -2, go down 2 and right 1
Answer:
-1 3/4
