They removed 4.5 tons in eight
Answer:
One number, let's call it x, is 6 more than twice the other number, let's say this number is y.
x= 2y+6
x+y=21
We're left with a system of equations.
If we substitute the first equation in the second we find the value of y.
(2y+6)+y=21
3y+6=21
3y=15
<u><em>y=5</em></u>
Now that we have found the value of y, we can take that value and substitute it in the second equation (since it's easier) to find the value of x.
x+ (5)=21
<u><em>x=16</em></u>
<u><em>Now to check if our answers are correct, we plug in both values into any equation and see if they equate.</em></u>
x+y=21
(16)+(5)=21
21=21
Our solution is correct!

Answer:
He spent 1.89 for 1 spool of thread
Step-by-step explanation:
1) 8.99 x 3 = 26.97 because He buys three yards of fabric at $8.99 per yard
2) 32.64 - 26.97 = 5.67 because we need to figure out what part of the total was spent on the spool of thread.
3) 5.67 / 3 = 1.89 because he bought three spoils of thread and I want to know the price of one.
