Answer:
208 1/8 hours
Step-by-step explanation:
The amount of time saved on each trip is ...
(3/4 h) - (1/4)(3/4 h) = (3/4)(3/4 h) = 9/16 h
There are 2×5×37 = 370 trips in the school year, so the total savings in time is about ...
370×(9/16 h) = 208 1/8 h
The answer should be 12x cm power of 2
Answer: x = t, y = 2t/3 + 2
Step-by-step explanation:
You want to write both x and y in terms of t
so if you rearrange 4x - 6y = -12 you get
-6y = -4x - 12
6y = 4x + 12
y = 2x/3 + 2
set x = t
and y = 2t/3 + 2
and that's it!
another one you could do is
x = t/2
y = t/3 + 2
or even
x = 3t/2
y = t + 2

~~~~~~~~~~~~~~~~~~~~~~~~~
Car #1: 300/43.2 = 6.9444 gallons
(Rounded) Car #2: 300/35.9 = 8.3565 gallons
~~~~~~~~~~~~~~~~~~~~~~~~~
(Rounded) Car #1: 6.9444*3.19 = $22.16 to re-fill their tank
(Rounded) Car #2: 8.3565*3.19 = $26.66 to re-fill their tank
~~~~~~~~~~~~~~~~~~~~~~~~~
(Rounded) Difference: $26.66 - 22.15 = $4.50
To re-fill Car 2's tank is approximately $4.50 more to re-fill Car 1's tank...
