So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .

Answer:
89–100
Step-by-step explanation:
Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...
80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90
Multiplying by 5 gives
400 ≤ 311 +x ≤ 450
Subtracting 311 gives the range for the fifth test grade.
89 ≤ x ≤ 139
Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...
89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test
Find the area of just the rectangle, which is 7(4) = 28

Answer:
75
Step-by-step explanation:
Simplify the following:
-6 - 7 (-4) + 5 - 8×(-9)/(-3) (-2)
-8×(-9)/(-3) (-2) = (-8 (-9) (-2))/(-3):
-6 - 7 (-4) + 5 + (-8 (-9) (-2))/(-3)
(-9)/(-3) = (-3×3)/(-3) = 3:
-6 - 7 (-4) + 5 - 83 (-2)
-7 (-4) = 28:
-6 + 28 + 5 - 8×3 (-2)
-8×3 = -24:
-6 + 28 + 5 + -24 (-2)
-24 (-2) = 48:
-6 + 28 + 5 + 48
