Answer:
Answer:
y = 13
Explanation:
You want to add the like variables:
(3x - y) = -1
+(-3x +3y) = 27
The x's cancel out:
2y = 26
Divide by 2 on both sides to get the y by itself and solve for y
y = 13
Step-by-step explanation:
2/5=w-3/2
remember that to solve we want to isolate 1 w one side by itself
also remember that we can do anything to an equation as long as we do it to both sides (except divide by zero)
2/5=w-3/2
so we add 3/2 to both sides to get rid of the 3/2
2/5+3/2=w+3/2-3/2
2/5+3/2=w+0
2/5+3/2=w
make the bottom numbers the same
the number is 10
2/5 times 2/2=4/10
3/2 times 5/5=15/10
4/10+15/10=w
4/10+15/10=(4+15)/10=(19)/10
w=19/10
so the steps are:
1. add 3/2 to both sides
2. make the denomenators of 2/5 and 3/2 the same so we can add them

the length 27
the width 25
Answer:
True
Step-by-step explanation:
Apply the distributive property
8a-(8a)- -8
Multiply 8 by -1
8a-8a- -8
Multiply -1 by -8
8a-8a+8
Simplify by adding terms
Subtract 8a from 8a
0+8
Add 0 and 8
8
Hope this helps :)
