Answer:
6.8% decrease
Step-by-step explanation:
a drop of 8% means that only 92% of 125 boys remained on honor roll from last year; .92 x 125 = 115
a drop of 5% means that only 95% of 80 girls remained on honor roll from last year; .95 x 80 = 76
total number of students on honor roll last year = 125 + 80 = 205
total number of students on honor roll this year = 115 + 76 = 191
percent of change = (191 - 205) ÷ 205 = -14/205 = -.068
-.068, which represents a 6.8% decrease
Answer:
5x - 5
Step-by-step explanation:
Allison: 9x
Adrian: 4x - 5
To find the difference, we subtract Adrian's number of miles, 4x + 5, from Allison's number of miles, 9x.
9x - (4x + 5) =
We think of the negative sign to the left of the parentheses as a -1, and we distribute it by multiplying -1 by 4x and multiplying -1 by 5.
= 9x -1(4x + 5)
= 9x - 4x - 5
Now we combine like terms. The only like terms are 9x and -4x.
= 5x - 5
