Answer:
x = 44
Step-by-step explanation:
So far, so good.
Now add the opposite of 0.8 to both sides.
0.2x = 8.8
And multiply both sides by 5 (equivalently, divide by 0.2).
x = 44
Answer:
Q - [R + S] - T = 10m + 5n - 24 ⇒ 1st answer
Step-by-step explanation:
* Lets explain how to solve the problem
- The value of Q = 7m + 3n
- The value of R = 11 - 2m
- The value of S = n + 5
- The value of T = -m - 3n + 8
* To simplify Q - [R + S ] - T substitute the value of each letter in
the expression
- Lets find R + S
∵ R = 11 - 2m
∵ S = n + 5
∴ R + S = 11 - 2m + n + 5 ⇒ coolect the like term
∴ R + S = 16 - 2m + n
∵ Q = 7m + 3n
∵ T = -m - 3n + 8
- Lets simplify the rest of the expression
- Remember (-)(-) = + and (-)(+) = -
∵ Q - [R + S] - T = (7m + 3n) - (16 - 2m + n) - (-m - 3n + 8)
∴ Q - [R + S] - T = 7m + 3n -16 + 2m - n + m + 3n - 8 ⇒ add like terms
∴ Q - [R + S] - T = (7m + 2m + m) + (3n - n + 3n) + (-16 - 8)
∴ Q - [R + S] - T = 10m + 5n - 24
Answer:
i belive the answer is 10
Step-by-step explanation:
Answer:
50%
Step-by-step explanation:
15 - 10)/10 x 100 = (5/10) x 100 = 50%
I think that the answer is B but no sure
