For every liter she used, she drove 8 kilometers. In this problem you are finding the unit rate. In order to do this you divide 48 (kilometers) by 6 (liters of gasoline).
48 Divided by 6 equals to 6 Kilometers
—- —-
6 Divided by 6 equals to 1 Liter
For the second question you divide the liter by 6. Amelia used 0.1666 liters of gasoline per kilometer. 0.1666 is equivalent to 1/6.
Answer:
Find the sum of the series
∑(4x−5)
such that
1≤x≤7
.
answer is 77
Step-by-step explanation:
Well, since it's already set up, all we do is divide -6 by 3/4 to get our x
So that means x=-8
Y=3x-4
Because your slope is 3 when you do change in y over change in x. Y intercept is neg 4.
