Hey there again, Bryanatwin2!
To solve for m in the equation, first we need yo distribute what's inside the parenthesis. We multiply -4 times what's in the parenthesis and we will get
-8m + 4 + 2 = 3m - 16
We combine like terms +4 +2 = 6
-8m + 6 = 3m - 16
Now we need to move all the m valued to one side
So we add 8m both sides to cancel it out on the left side and we are left with
6 = 11m - 16
Now we need to isolated 7m and to do so we add 16 to both sides to cancel it out on the right and we end up with
22 = 11m
No we have to isolate m by dividing both sides by 11 since m it's being multiplied by 11
And we get
2 = m
or m = 2
So the answer is C
Thank you for using Brainly.
See you soon!
29.99 * 55\100 = 16.49 $
29.99 - 16.49 = 13.5 $
well #7 is a solution.
y= 9x (4,36)
9 times 4 = 36
36/9=4
so the ordered pair is a solution.
y=3x-5 (7,16)
3 times 7 -5= 16
so once again the ordered pair is a solution.
Hoped this helped.
Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
