Answer:
10x +6y - 14
Step-by-step explanation:
3x - 2y = 13x + 4y = 14
3x = 13x + 6y = 14
-10x = 6y = 14
10x + 6y - 14
FInd the circumference of the tire:
C = 2 x PI x r
C = 2 x 3.14 x 14
C = 87.92 inches.
For every revolution of the tire it travels 87.92 inches.
In one minutes the car travels 87.92 x 120 = 10,550.4 inches.
In 5 minutes the car travels 10550.4 x 5 = 52,752 inches.
52,752 / 12 = 4,396 feet
1 mile = 5280 feet
4396 / 5280 = 0.833 miles
I calculated 3 different measurements. Use the one needed.
Answer:
What?
Step-by-step explanation:
is this your whole question?
If you mean:
1/(3a^2)-1/a=1/(6a^2) we need a common denominator of 6a^2
2/(6a^2)-6a/(6a^2)=1/(6a^2), multiplying all terms by 6a^2 then:
2-6a=1 subtract 2 from both sides
-6a=-1 divide both sides by -6
a=1/6
8.3 because .3 is in the tenths place but .03 is in the hundredths place, which is smaller.
