Y=10x+20
10x because the price is $10 a class
+20 because it costs $20 for the monthly subscription
Answer:
x=5/2
Step-by-step explanation:
4x-2=2x+3
1) Add 2 to both sides:
4x=2x+5
2) Subtract 2x from both sides:
2x=5
3) Divide both sides by 2:
x=5/2
Answer:
m = 0
Step-by-step explanation:
Given
7m + -10 = -10
Positive negative gives negative.
So the expression can be rewritten as
7m - 10 = -10
Add 10 to both sides of the equation
7m - 10 + 10 = -10 + 10
7m = 0
Divide both sides by 7
7m /7 = 0/7
m = 0
3*4*3-2*4^2 = 36-32 = 4

Of 85% of cars sold where not black then 100-85% where black = 15%
let the number of cars sold be y
then 15%*y=300
y= 300 divided by 15%
= (300*100)/15
=2000
therefore 2000 cars were sold
