-8(-3 3\4+6)
-8(-9\4+6)
18-2
answer=16
8 students can be in a row.
If the same amount of students must be in each row across the grades, determine their greatest common factor. That would be 8 (8*2=16, 8*3=24). Any more than that, and the rows are uneven. There can be a max of 8 people in a row (2 rows for 6th grade, and 3 rows for 7th)
Hope it helps! I can explain further if needed

That's correct it actually helped me alot... Thanks
First rearrange the first equation and solve it for 'm':
m + n = 5
Subtract n to both sides:
m = -n + 5
Now plug in -n + 5 for 'm' in the 2nd equation:
-n + 5 - n = 3
Combine like terms:
-2n + 5 = 3
Subtract 5 to both sides:
-2n = -2
Divide -2 to both sides:
n = 1
Now we can plug this back into any of the two equations and solve for 'm':
m + n = 5
m + 1 = 5
Subtract 1 to both sides:
m = 4
So our full answer is (4, 1)
Area of small triangle = 1/2bh = 1/2(5)(2) = 5
area of large triangle = 1/2bh = 1/2(6)(4) = 12
area of trapezoid = 1/2(b1+b2)h = 1/2(11+14)(2) = 25
area of figure = 5 + 12 + 25 = 42
