0.2y = 0.5x + 0.1
Reorder the terms:
0.2y = 0.1 + 0.5x
Solving
0.2y = 0.1 + 0.5x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '0.2'.
y = 0.5 + 2.5x
Simplifying
y = 0.5 + 2.5x"</span>

Answer:
1/56
Step-by-step explanation:
P( bear is first) = bear/ total = 1/8
Then there are 7 animals left
P( zebra is 2nd) = zebra /total = 1/7
P( bear, then zebra) = 1/8 * 1/7 = 1/56
Problem 1
subtract 3 x
5y=-3x+11
divide 5
y=3/5x+2.2'
Problem 2
add 5x
7y=5x+9
divide 7
y=5/7x+1.3'
'notice'
you can put 2.2 into a fraction (11/5) and 1.3 (9/7) if your teacher allows it, but i put them into decimals
V = 4/3πr³
V= 4/3π(4.8)³
V= 4/3π(110.592)
V=147.456π
