Answer:
24 :)
Step-by-step explanation:
2 / 3 x 36 = ?
First of all, note that 36 is the same as 36/1 since 36 divided by 1 is 36. Therefore, start by setting up the problem like this:
36 / 1 x 2 / 3
Multiply the numerators together (36 x 2 = 72) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:
72 / 3
The greatest common factor of 72 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
24 / 1
Convert the improper fraction above to a whole number to get the answer:
24

Answer:
Step-by-step explanation:
<u>Given</u>
- Q = 7m + 3n,
- R = 11 - 2m,
- S = n + 5,
- T = -m - 3n + 8
<u>Simplify [Q - R] + [S - T]</u>
- (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
- 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
- m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
- 10m + 7n - 14
