Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
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:
Q = 3
Step-by-step explanation:
3 * P + 7 * Q + 15 * R = 102
7Q = 102 - 3P - 15R
Q = (102 - 3P - 15R)/7
Try P = 2; R = 3
Q = 51/7 not an integer
Try P = 2; R = 5
Q = 21/7 = 3
Solution: P = 2; Q = 3; R = 5
Answer: Q = 3
Let us assume that the first company the cab flat rate is 5$ and the cap driver charges 2$ per mile .for the second company the cab flat rate is 3$ and the cab driver charges 3$ per mile.
a. the company charges per ride at least 5$ and an extra 2$ per mile
b.the equation we will choose is slope intercept since we know the
y-intercept which is the cab flat rate .
y=mx+b
where
m :is the slope
b:is the y-intercept
y:total amount
x. is the milage
total amount=2x+5.
c.the slope will be 2$ which is the change in amount per mile.the y-intercept will be the cab's flat rate.
1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.
1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.
The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.
