A.....p - 1
w = ------
........2
B. w = p - 2L
C.....p - 2L
w = -------
........2
D. w = p - a
*The dots are so everything lines up to look like a fraction.
I know I should have paid more attention in high school, but now I could really use some help with a few math questions......Thanks in advance!
"Suppose you're given the formula R = s + 2t. If you know that s is three times greater than t, how could you rewrite the formula?"
A. R = 3(s + 2t)
B. R = 3(s + t)
C. R = 5s
D. R = 5t
