Answer: Blll's family has 70% of driving left.
Step-by-step explanation:
The total mileage of the trip = 3,000 miles.
miles driven so far = 900miles
Miles of diatance left = 3000- 900=2100
Percentage of driving left = Miles of diatance left / Total miles to cover x 100
=2100/3000 x 100
= 7/10 x100
70%
There are six of them.
2 / (1/3) = 6
The answer: x=857 and y=-401
Set up the two equations
X+2y=55
2x+y=1313
Solve the system of equations by elimination
2x+y=1313
-2x-4y=-110
Add each of the corresponding terms together
-3y=1203
Divide by -3
Y=-401
Plug y back into one of the original equations
X+2(-401)=55
X-802=55
X=857
100. Percent means out of hundred, so one percent means one out of a hundred, two percent means two out of a hundred, etc.
