Pls 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 (not this one)

-m + 2n - 2

Step-by-step explanation:

R - [S + T]

Since we know  R = 11 - 2m, S = n + 5, and T = -m - 3n + 8,

we can substitute them in.

Replacing R,S and T

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

Combine inside the brackets

11 - 2m - [n  - 3n-m +5+ 8]

11-2m -[ -2n -m +13]

Distribute the minus sign

11-2m - -2n --m -13

11-2m +2n +m -13

Combine like terms

m-2m +2n +11 -13

-m +2n -2

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
