First, convert cm to inches.
50/2.54 is roughly 19.69
There are 12 inches in a foot, so divide the 19.69 by 12.
19.69/12 is roughly 1.64
So the answer is C
m=52h
52 is the miles/hour, and you’re going for 4 hours, which is 208 miles.
It's 10 - 4
moving decimal over to the right makes a negative exponent.
Answer:
See below.
Step-by-step explanation:
Part A.
I'm changing the l and w to capital letters, so you don't confuse the l (small-case L) with a 1 (one).
P =2(L + W)
Since W is on the right side, switch sides to end up with W on the left side.
2(L + W) = P
Since the quantity in parentheses is being multiplied by 2, we divide both sides by 2.
L + W = P/2
L is being added to W, so we subtract L from both sides.
W = P/2 - L
Part B.
First, I switched sides to have W on the left side. Then, I divided both sides by 2. Finally, I subtracted L from both sides.
