Answer:
The answer is 7(5x+4y)
Step-by-step explanation:
Well you would have to first find what number is able to go in both numbers.
7 can go into 35 by 7·5
7 can also go into 28 by 7·4
So now we would simplify this by putting this in a distributive equation.

Answer:
160
Step-by-step explanation:
(2.5 x 2)+(1.5 x 2) =8 (perimeter of scale)
8x20 = 160
Answer:
A-B really simple.
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
A triangle's angles add up to 180
Also, angles on a straight line add up to 180
180-100 = 80
80+70=150
180-150=30
To solve this equation, we will need to isolate y, the variable. These are the steps that follow:
1. Add 0.3y to each side.
2. Subtract 21.3 from each side.
3. Divide both sides by 5.4y.
Try and figure it out yourself! If you have trouble...
The answer is y = -8.5
