The answer is to the question is 9
Answer: B. 3x + 1/5
tom's pencil is longer than Ellen's pencil:
5x + 2/5 - (2x + 1/5) = 5x - 2x + 2/5 - 1/5 = 3x + 1/5 (cm)
Step-by-step explanation:
Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then
10x^2 = 5x
So either x = 0, giving 0=0. Or divide by 5x
2x = 1
x = 0.5
Answer:
the estimated difference is 4
Step-by-step explanation:
The estimated difference of 12 9/11 - 8 13/15 would be rounding the fractions to a whole number
12 9/11 becomes 12 11/11 which is 13
8 13/15 becomes 8 15/15 which is 9
we rounded each fraction up since each fraction was above the half way mark so the new equation is,
13 - 9 = 4
