Six would be your answer
Step-by-step explanation:
2y-9= y-2
-y -Y
y-9=-2
y=-2+9
y=6
The equation c = 2.95g shows how much it costs to buy gas at a gas station on a certain day. In the equation, c represents the cost in dollars, and g represents
(a) four (gallons of gas, cost) pairs that fit this relationship.
Plug in some values for g and find out C
c = 2.95g
g= 1, C= 2.95(1) = 2.95
g= 2, C= 2.95(2) = 5.9
g= 3, C= 2.95(3) = 8.85
g= 4, C= 2.95(4) = 11.8
four pairs are (1,2.95) (2,5.9) (3,8.85) (4,11.8)
2. Create a table or graph of the relationship.
Use the above points we got from part (a) for graphing
The graph is attached below
(3) What does 2.95 represent in this situation?
g= 1, C= 2.95(1) = 2.95
This means when 1 gallon purchased then the cost is 2.95 dollars
2.95 represents the cost of 1 gallon of gas
(4) Jada's mom remarks, "You can get about a third of a gallon of gas for a dollar."
c = 2.95g
c is the cost , and g is gallons
cost is 1 dollar so we replace c with 1
1 = 2.95 g
Divide by 2.95 on both sides
That is one third of a gallon of gas
So she is correct.
