Answer:

y=45x

y represent the distance traveled by the car in x gallons of gas.

Step-by-step explanation:

Given:

A car travels 45 miles  on one gallon of gas.

We need to calculate distance covered by the car in x gallons of gas.

Let y represent the distance traveled by the car in x gallons of gas.

We know that distance traveled by the car directly varies with the amount of gas.

So, we havey ∝ x

Thus y=kx

where k represents the distance traveled by car in 1 gallon of gas.

From the data given we know k=45

So, the expression to find the distance the car can travel using x gallons of gas is written as:

y=45x

If y varies directly as x and y-21 when x<br> is 7, find x when y = -5.
klasskru [66]

Step-by-step explanation:

Since, y varies directly as x:

\therefore \: y = kx..(1) \\ (k = constant \: of \: proportionality) \\ at \: y = 21 \: and \: x = 7 \\ 21 = k \times 7 \\ k =  \frac{21}{7}  = 3 \\ plugging \: k = 3 \: in \: equation \: (1) \\ y = 3x..(2) \\ plugging \:  \: y =  - 5  \: in \: (2)\\  - 5 = 3x \\ x =  \frac{ - 5}{3}  \\   \:  \:  \:  \:  \:  \: \huge \red{ \boxed{x =  -  \frac{5}{3} }}

A candidate took a phone poll of 114 people and found that 87 said they would vote for the other person.There are 9918 people in
Dima020 [189]
87 / 114 = x / 9918....87 people to 114 = x people to 9918
cross multiply
(114)9x) = (87)(9918)
114x = 862866
x = 862866/114
x = 7569 <===
