Answer:
1st one is (0.03)(250)
2nd one is $7.50
3rd one is $30.00
Step-by-step explanation:
The equation y = -0.04x + 12 gives the number of gallons of gas in your car where x is the number of miles drivene
easy
y=gas left
x=miles
sub 200 for x
y=-0.04(200)+12
y=-8+12
y=4
4 gallons left
Answer:
c=4
Step-by-step explanation:
–2c = –c − 4
add c to both sides
-1c=-4
divide both sides by -1
c=4
Subtract 20n from both sides of the equation.
n^2+100-20n=0
factor using the perfect square rule.
(n-10)^2=0
set the n-10 equal to 0.
n-10=0
add 10 to both sides of the equation.
n=0
