The scale factor is the number that gets multiplied by the other number.

The original coordinates were (3,3) and the new one was (9,9) so the scale factor is 3 because 3x3=9

Irina-Kira [14]

Answer:

Step-by-step explanation:

So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4

adding this all up we get 8x-7=49, so 8x = 56 or x = 7

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.
