Answer:
m = -1 is your answer.
Step-by-step explanation:
What you do is you have to get m by itself.
<em>m = -(4 + m) + 2</em>
<em>m = -4 + -m + 2</em>
<em>2m = -2</em>
m = -1 is your answer.
Answer:
1350
Step-by-step explanation:
Initially 90 squirrels were tagged out of a total population of x squirrels.
Similarly, 42 squirrels out of a sample of 630 squirrels had tag
We can use ratio equality to find the total population x.
42:90=620:x
Cross multiplying
42 X x = 630 X 90
Dividing both sides by 42
The total number of squirrels in the city park is 1350.

Hello from MrBillDoesMath!
Answer: x = +9
Discussion:
-59 = 3x -2 (7x -20) or
-59 = 3x - (2*7)x - 2 ( -20) or
-59 = 3x -14x + 40 or
-59 = -11x + 40. Subtract 40 from each side
-59 - 40 = -11x or
-99 = -11x
or x = + 9
Thank you,
MrB
