10m+7n-14

Step-by-step explanation:

The answer is 10m + 7n - 14

Step-by-step explanation:

Q = 7m + 3n

R = 11 - 2m

S = n + 5

T = -m - 3n + 8

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

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

Solve the terms in the bracket first

That's

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

( 9m + 3n - 11 ) + ( m + 4n - 3)

Remove the brackets

That's

9m + 3n - 11 + m + 4n - 3

Group like terms

9m + m + 3n + 4n - 11 - 3

The final answer is

10m + 7n - 14

Hope this helps you

[Q - R] + [S - T]=10m+7n-14

Step-by-step explanation:

Given : Q = 7m + 3n,

R = 11 -2m,

S = n + 5, and

T = -m - 3n + 8

Now  , Q-R= 7m + 3n-(11 - 2m)

Q-R= 7m +3n-11+2m    [ ∵ (-)(+)=(-) and (-)(-)=(+)]

[Note : when -1 is outside the parenthesis it indicates that -1 should be multiplied with each of the terms present inside the parenthesis .]

Q-R= 9m +3n-11  [Combine like terms.]

S-T=n + 5-(-m - 3n + 8)

S-T=n + 5+m+3n-8    [ ∵ (-)(+)=(-) and (-)(-)=(+)]

S-T=4n +m-3    [Combine like terms.]

Now, [Q - R] + [S - T]=[9m +3n-11]+[4n +m-3]

=9m +3n-11+4n+m-3

=10m+7n-14  [combine like terms]

Hence, [Q - R] + [S - T]=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

10m + 7n - 14

Steps:
[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]
7m + 3n -11 + 2m + n + 5 + m + 3n - 8
10m + 7n - 14
(Q-R)+(S-T)
(7m+3n-11-2m)+(n+5- -m-3n+8)
5m+3n-11+-2n+-3+-m
4m+n+-14
(7m+3n-11-2m)+(n+)-3n+8)
5m+3n-11+)-2n+8
6m+n+2

that's what i got, and i'm in high school. i'm sorry try asking your teacher in the morning.

The answer is 10m+7n-14 because you need to subtract
