An electric car can travel at top speed for 107 km on 5 h charging time. If the car died after just traveling 65 km at top speed, how long a charge could it have held?
A.) 4h B.) 2.5h C.) 3h D.) 3.5h
9514 1404 393
Answer:
C.) 3 h
Step-by-step explanation:
If you assume the distance is proportional to the charge time, then ...
x/5 = 65/107
x = 5(65/107) ≈ 3.04
The car may have held about a 3-hour charge.

Step-by-step explanation:
we have
d=p(1-r/100)^t
10000=20000(1-15/100)^t
10000/20000=85/100^t
1/2=0.85^t

Solve this system of equations:
2x + 10y= 24
X = y-6
Answer:
(-3,3)
Step-by-step explanation:
Substitute x for the first equation
2(y-6) + 10y= 24
2y-12+10y=24
12y=36
y=3
Now solve for x by plugging in 3
x = 3-6
x=-3
Answer:
x = -3
y = 3
Step-by-step explanation:
2x + 10y = 24
x = y - 6
plugin x = y - 6 into the first equation
2(y - 6) + 10y = 24
solve for y
2y - 12 + 10y = 24
12y = 36
y = 3
plug y back into x = y - 6
x = 3 - 6
x = -3
