Answer:350
Step-by-step explanation:
Just take away 9,550 - 9,200 = 350
Answer:
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Step-by-step explanation:
The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.
Given;
Number of fiction books = 2,600
Number of books = 4,000
let the percent of books that are fiction be x
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
This is what you do.
x - 2y = -8
4x - 3y = -17
Add 2y to both sides on the first equation.
x = 2y - 8
4x - 3y = -17
Now substitute the x value.
4(2y - 8) -3y = -17
8y - 32 - 3y = -17
Combine like terms
5y - 32 = 17
Add 32 to both sides.
5y = 15
Divide.
y = 3
Now find x by plugging in 3 into 1 equation.
x - 2(3) = -8
x -6 = -8
Add 6 to both sides.
x = -2
So you solution is (-2, 3).
I hope this helps love! :)
