Answer: $7
Step by step explanation: so first, we have to form any equation to show that some amount of money was added to eight dollars to get a total of fifteen dollars. Our equation becomes 8+x=15
Where eight is the origins amount, x is the amount that's added to the original amount and fifteen is the final amount.
We then move eight to the other side as a negative number
x=15-8
Therefore, x is equal to seven dollars.
First you multiply 3 x 1000 which is 3,000. Then you too 2 x 100 which is 200. Lastly you subtract 3000 from 200 and you get 2800.
You mean their sum is 12?
A) x + y = 12
B) x -y = 4 then we add both equations:
2x = 16
x = 8
y = 4
there are 3 tenths in 8.32
Answer:
3.
Step-by-step explanation:
3(n + 4) = 21
3n + 12 = 21
3n = 21 - 12 = 9
n = 3.
