Amy drives her car until the gas gauge is down to 1/8 full, then she fills the tank to capacity by adding 14 gallons. What is th
Kazeer [188]

Answer:

Amy's car tank capacity is 16 gallons.

Step-by-step explanation:

Let the capacity of the tank be 'x'

Given:

Amount of gas in the car till it is refilled = \frac{1}{8}\times x = \frac{1}{8}x \ gallons

Amount of gas added = 14 gallons.

We need to find the capacity of the tank.

Solution:

Now we can say that

Total Capacity of the tank is equal to sum of Amount of gas in the car till it is refilled and Amount of gas added.

framing in equation form we get;

x=\frac{x}{8}+14

Combining the like terms we get;

x-\frac{x}{8}=14

Now making the denominators common we will use L.C.M.

\frac{8x}{8}-\frac{x\times1}{8\times1}=14\\\\\frac{8x}{8}-\frac{x}{8}=14\\\\\frac{8x-x}{8}=14\\\\\frac{7x}{8}=14

Now multiplying both side by 8 we get;

\frac{7x}{8}\times 8=14\times8\\\\7x = 112

Now dividing both side by 7 we get;

\frac{7x}{7}=\frac{112}{7}\\\\x=16\ gallons

Hence Amy's car tank capacity is 16 gallons.

Someone factor x^2+18x+77
Ipatiy [6.2K]
77 is a multiple of 11, as i'm sure you know--the double numbers like 22 and 55, one of the factors are always 11.

77 is factored down into 11 and 7--which, when you add those, luckily equal 18.

(x + 11)(x + 7) is your factorization.
