3( 1/2 - y) = 3/5 + 15y
Applying distributive property:
3*1/2 - 3y = 3/5 + 15y
3/2 - 3y = 3/5 + 15y
3/5 is adding on the right, then it will subtract on the left
3y is adding on the left, then it will subtract on the right
3/2 - 3/5 = 15y + 3y
15/10 - 6/10 = 18y
9/10 = 18y
18 is multiplying on the right, then it will divide on the left
9/10*1/18 = y
1/10*1/2 = y
1/20 = y
Total surface area equals area of 5 rectangular faces + 2 pentagonal faces
Area of 5 rectangular faces


Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.


The toatal surface area is

The correct answer is A
Answer:
0.75
Step-by-step explanation:
-6x+2x=6-9
-6x+2x=6-9
-4x=-3
x=-3/-4
x=0.75
Hope this will help ya!
Can u give me brainliest hehrhe
The equation would be ... Y = 2x + (-5)
