Given: q = 7m + 3n, r = 11 - 2m, s = n + 5, and t = -m - 3n + 8.

simplify [q - r] + [s - t].

10m + 5n - 24
10m - 5n + 24
10m + 7n - 14
10m - 7n - 14

10m - 7n - 14

Step-by-step explanation:

Given Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8

[Q - R] + [S - T].

= (7m + 3n - 11 + 2m) + (n + 5 + m + 3n - 8)

collect all the like terms

= 7m +2m +m +3n + n + 3n - 11 - 8 + 5

= 10m + 7n - 14

The third option  10m - 7n - 14 is right

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
