Julie bought g gallons of gasoline for $4.95 per gallon and c cans of oil for $5.25 per can. a. What expression can be used to determine the total amount Julie spent on gasoline and oil?
b. If she bought 8.6 gallons of gasoline and 9 cans of oil, how much did she spend in all?
a. Choose an expression that represents the amount that Julie spent in all.
OA. 4.950.5.25g
OB. 4.959.5.25c
OC. 4.950 +5.25g
OD. 4.95g +5.25c

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
