Answer:
m = 9
It means that you are multiplying each of the values inside the parentheses by 2.
Step-by-step explanation:
2(m + 2) = 22
2m + 4 = 22
2m + 4 - 4 = 22 - 4
2m = 18 -Divide both sides by 2
m = 9
If you apply the linear combination method to the system like:
<span>4(.25x + .5y = 3.75) → x + 2y = 15
(4x – 8y = 12) → x – 2y = 3
2x = 18
Then you can be sure that the solution of all this system is: (9,3). Hope this si what you were looking for</span>
Answer:
1,3,5
Step-by-step explanation:
81 is a perfect square so it can be written as an integer
11.8 is rational because it can be written as a fraction (107/9)
sqrt(6) isn't a perfect square so it is irrational
3/7 is a fraction so it is rational
8.57 is a terminating decimal so it is rational
Answer:
Step-by-step explanation:
y = 1/2x + 3
Answer:
x = -16
Step-by-step explanation:
-4x - 13 = 51
-4x = 51 + 13
-4x = 64
x = -16
