The answer is 7.. I think ♀️
Answer:
She will need 13.2 gallons to drive 286 miles
Step-by-step explanation:
Step 1
Consider the expression below;
T=G×N
where;
T-total miles traveled
G-number of miles per gallon
N=quantity of gas consumed
This can also be expressed as;
Total miles=number of miles per gallon×number of gallons
In our case;
T=260 miles
G=unknown
N=12 gallons
replacing;
260=G×12
12 G=260
G=260/12
G=21.67 miles per gallon
Step 2
Using the same expression;
T=G×N
where;
T=286 miles
G=21.67 miles per gallon
N=unknown
replacing;
286=21.67×N
21.67 N=286
N=286/21.67
N=13.2 gallons
She will need 13.2 gallons to drive 286 miles
Answer:
y = 4x
Step-by-step explanation:
If y is directly proportional to x (which is what I assume you are meaning in this question), this means that
y = kx, where k is the constant of proportionality.
To find k, we simply substitute in the given x and y values, and solve for k. i.e we to get:
8 = k x 2.
k = 8/2 = 4.
so y = 4x
