Answer: -x^2 + 15x
Step-by-step explanation:
Let's give Cindy's age a variable.
Cindy's age = x
Cindy multiplies her age by 5
x(5)
Subtracted by 12
x(5) - 12
Divide by 3
(5x - 12)/3
The result was 16
(5x - 12)/3 = 16
Let's solve
Multiply both sides by 3
(5x - 12) = 48
Open brackets
5x - 12 = 48
Add 12 to both sides
5x = 60
Divide by 5 on both sides to isolate x
x = 12
Cindy is 12 years old.
Answer: Let's solve for x.
2x−10y=10
Step 1: Add 10y to both sides.
2x−10y+10y=10+10y
2x=10y+10
Step 2: Divide both sides by 2.
2x
2
=
10y+10
2 answer
x=5y+5
Step-by-step explanation:
Let's solve for s.
sx+9y=9
Step 1: Add -9y to both sides.
sx+9y+−9y=9+−9y
sx=−9y+9
Step 2: Divide both sides by x.
sx
x
=
−9y+9
x
s=
−9y+9
x
Answer: hope this helps:)
s= -9y+9/x
