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

simplify r - s + t.
m - 2n - 2
-m + 2n - 2
3m - 4n + 14
-3m - 4n + 14

The answer is=-3m-4n+14

Step-by-step explanation:

Step-by-step explanation:

Step 1: Express terms in the form R-S+T

Where R=11-2m, S=n+5, T=-m-3n+8

Replace values for R, S and T in R-S+T= (11-2m)-(n+5)+(-m-3n+8)

Step 1: Collect all the like terms

Open the brackets

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

Like terms are similar variables, for example;

(-2m, -m) are all like terms since they have a common variable (m)

(-n, -3n) are also like terms since they have a common variable (n)

(11,-5,8) are constants

Step 2: Solve

-2m-m-n-3n+11+8-5=-3m-4n+14

The answer is -3m-4n+14

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
