Answer:
7 number ans is b because 2 times the sum of a and b means 2×(a+b)
5 meters = 16 feet and 4.85 inches
5000000 milliliters
500 centimeters
He will have to pay $3.25.
Let the number of miles traveled by a driver be x
The toll paid by the driver is then represented as $y.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = $5.50
Hence, He will have to pay $3.25.

Answer:
Improper fraction (-81t/ 4s)
Mixed number (-20 1/4) (t/s)
Step-by-step explanation:
Multiply the numerators
9(9t) = 81t
Multiply the denominators
4s* (-1) = -4s
Put the numerator over the denominator
81t / -4s
If they want the answer as an improper fraction -81t/4s
If they want a mixed number
81/4 = 20 with 1 left over
20 1/4
Then multiply by (-t/w)
(-20 1/4) (t/s)
