Use Substitution or Elimination
1. pick one equation and solve for a variable
6p + 1m = 9
1m = 9-6p
m = 9 - 6p/ 1
m= 9-6p
2. substitute m into one of the equations given
4p + 2 ( 9-6p) = 10
4p + 18 - 12p = 10
4p - 12p = 10 - 18
-8p = -8 (divide both sides by -8)
p = 1
3. Insert p=1 into any of the equations
6p+1m = 9
6(1)+1m =9
6 + 1m = 9
1m = 9-6
1m= 3
m = 3

Answer:
$642
Step-by-step explanation:
To calculate sales tax, you multiply the percentage by the price. In this case it would be 600 x 0.07 which is 42. Then you add them together which would be 600 plus 42 which equals 642.
Answer:
c meter
Step-by-step explanation:
The given point (t, P) is (0, 1000), and the slope is given as ∆P/∆t = 30. Using the point-slope form of the equation for a line, the equation can be written as
... P = 30t + 1000
