52+4y=12
We move all terms to the left:
52+4y-(12)=0
We add all the numbers together, and all the variables
4y+40=0
We move all terms containing y to the left, all other terms to the right
4y=-40
y=-40/4
y=-10

3.1-3y=18
3.1-3y-(18)=0
-3y-14.9=0
-3y=14.9
y=14.9/-3
y=-4+2.9/3
Answer:
Step-by-step explanation:
180 - 152 = 28
2x + 28 = 180
2x = 152
x = 76
I would assume you're referring to this test? if so the answer is
a, d and e
Believe it or not, the two areas are the same.
The base of the rectangle is PQ
The height of the rectangle is PS
Now look at the parallelogram.
The base is PQ
The height is PS
The area has to be the same in both cases. There is no other way to interpret what is happening.
800-50=750 so 750+50=800 the dryer maybe go be 750
