Y = 10x
Plug in $260 for y.
260 = 10x
Divide by 10.
x = 26
Sue babysat for 26 hours.
The two equations given are
3x + y = 17 and 4x - y = 18
Now we will first take one equation
3x + y = 17
Then
y = 17 - 3x
Now replacing the value of y in the second equation we get
4x - y = 18
4x - (17 - 3x) = 18
4x + 3x - 17 = 18
7x = 35
x = 35/7
= 5
Putting the value of x in the first equation we get
3x + y = 17
(3 * 5) + y = 17
15 + y = 17
y = 17 - 15
y = 2
So the value of x is 5 and y is 2
A unit multiplier is a conversion factor of value 1 that we can use to convert quantities.
We want to convert 123 pounds per mile to ounces per centimeter.
First, we are going to express the quantity to convert as a fraction:
123 pounds per mile=

Next, we are going to find our multipliers:
- We know for our problem that there are 5,280 feet in 1 mile, so our first multiplier will be:

- We also know that there are 16 ounces in 1 pound, so our second multiplier will be:

- We know that there are 12 inches in 1 foot, so our third multiplier will be:

- We know that t<span>here are approximately 2.54 cm in 1 inch, so our fourth multiplier will be: </span>

Now we can put all our multipliers together:

We can conclude that the answer is
0.01
20/66 divided by 2 = 10/33
6,317,927 can be a 7 digit number that rounds to 6,300,000.
Hope this helps.
