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.

Please help i am new here

DENIUS [597]

Answer: 1. 3/8-1/4=1/8

2. 3/8+1/4=5/8

3. x=5/8

Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8

2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8

3. look at number 2. and the answer is x= 5/8

Fraction from or decimal form but has to be rounded

Alekssandra [29.7K]

Answer:

x = $\frac{25}{6}$

Step-by-step explanation:

Given expression is,

$2x-\frac{11}{4}x=-\frac{25}{8}$

$\frac{8x}{4}-\frac{11}{4}x=-\frac{25}{8}$

$\frac{8x-11x}{4}=-\frac{25}{8}$

$-\frac{3x}{4}=-\frac{25}{8}$

$\frac{3x}{4}\times 4=\frac{25}{8}\times 4$

$3x=\frac{25}{2}$

$\frac{3x}{3}=\frac{25}{2}\times \frac{1}{3}$

x = $\frac{25}{6}$

Unit rate of. 15 degrees. in 2 hours

schepotkina [342]

<span>Ok, so we need to find the unit rate of 15 degrees in 2 hours.
this is a very simple question, it says here that in 2 hours, there are 15 degrees.
Thus we need to find the unit rate of this given situation per hours.
=> hour many hours are there? The answer is 2
so let us divide 2 by 15 to get the unit rate of the given situation
=> 15 degrees / 2 hours
=> 7.5 degrees / hours
Thus, the unit rate of 15 degrees per 2 hours is 7.5 degrees per hour.</span>
