Answer:
an average 7th grader owns 3 pairs of sneakers
X 3/5 =2x+15=2x=15-2x=13
answer 13
Well 5/6 x 3/4 is 15/24 so you’d do 24 dots across in 15 rows
Subtract 13.09 from 21.59 giving you 8.5. Since the amount of space on both the left and right margin have to be equal you would divide by 2 to get 4.25 on the left margin as well as the right.
Xy is the number
A) x + y = 7
B) 10y + x = 10x + y + 9
collecting terms of equation B
B) -9x + 9y = 9
multiplying A) by 9
A) 9x + 9y = 63 then adding it to equation B)
B) -9x + 9y = 9
18y = 72
y = 4
x = 3
The number is 34
