Answer:
y = -3x -72
Step-by-step explanation:
This is how I'd set it up:
405/20 = 243/x
this means the mpg (miles / gallons) for 1 situation is the same as the mpg for the other situation (because the rate is the same)
then just cross multiply and solve:
405x=243*20 or 405x=4860 or x = 12
he would need 12 gallons of gas for 243 miles
Answer:
764-118=s
Step-by-step explanation:
The school has 764 students. Taking away the third graders will let you know how many are left in the other grades. Please marl brainliest.
Oh, and assuming you want the total number in each grade, 1-6? its (764-118)%5=s
From the given statement, we know the following...
0.35x = $247 where x = the orginial number
So if we solve for x by dividing by 0.35
x = $247/0.35 = $705.71
