Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.
borishaifa [10]

Answer:

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

simplify the mathematical expressions and arrange them in order of their values from least to greatest​
Helen [10]

Answer:

See the first attachment. The numbers indicate the order 1=least, 5=greatest.

Step-by-step explanation:

This is a calculator exercise. Put the numbers in your calculator and have it tell you the result. Don't forget that (ab)/(cd) = ab/c/d if you don't use parentheses.

See the 2nd and 3rd attachments for the values of the expressions.

___

You can estimate values as follows (top to bottom):

1. 4·9·10^(8-5) ≈ 36·10^3

2. 7·8·10^(5-2) ≈ 56·10^3

3. (7·9)/(8·4)·10^(5-7+2+3) ≈ 2·10^3

4. (8·10)/(8·6)·10^(4+1-11+8) ≈ 1.7·10^2

5. (2·6)/(3·5)·10^(4+3+2-2) ≈ 0.8·10^7

These are crude estimates, but sufficiently close to put the numbers in order as required.
