Perimeter = 2 1/8 + 3 1/2 + 2 1/2 = 7 (1 + 4 + 4)/8 = 7 9/8 = 8 1/8
Answer:
x=
−1
2
y+
25/2
Step-by-step explanation:
Let's solve for x.
2x+1y=25
Step 1: Add -y to both sides.
2x+y+−y=25+−y
2x=−y+25
Step 2: Divide both sides by 2.
2x
2
=
−y+25

Answer:

Step-by-step explanation:
The formula of a surface area of a cylinder:

r - radius
H - height
We have r = 40mm and H = 50mm. Substitute:

Answer:
A is 15, B is 1, and c is 4!
Step-by-step explanation:
This is because 15 (rooted number) would be the main focus, and since the x (normally by the rooted number) doesn't have a label (like 2x, 3x, etc.) it will be one. Then, the 4 (last number) is c (since it is on the outside and is likely the divisor.
Good luck!
