12x^2-4x=0
144x^2-4x=0
140x^2=0
/140 /140
x=0
Answer:
Step-by-step explanation:
250 divided by 20= 12.5
So 12.5 miles per gallon.
Answer is -10.
x-intercept, y=0, substitute for y in the equation. you will have -2x+5(0)=20
-2x =20
x =20/-2
x=-10
Answer:
see explanation
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4

Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )

I multiplied 20,000 by 0.13 and got 2,600. Then I subtracted 20,000 from 60,000 to get 40,000. Finally I did 40,000 / 2,600 and got 15.4
