Translate<br> Solve the equation.<br> 3m= 5(m + 3)-3<br> HELP
kvasek [131]

Answer:

m = -6

Step-by-step explanation:

3m= 5(m + 3)-3

Distribute

3m = 5m +15 -3

Combine like terms

3m = 5m +12

Subtract 5m

3m-5m = 5m+12-5m

-2m = 12

Divide by -2

-2m/-2 = 12/-2

m = -6

Kalon and his friend Marna own a chimney sweep service company. Working together, they can clean a chimney in 1 5/7 hours. If it
QveST [7]
The amount of work done by Kalon in an hour is equal to 1/4. This is based on his time to finish the job. Letting x be the number of hours Marna can finish the job alone will let her finish 1/x of the job in an hour. If their rates are added together and multiplied by the number of hours they worked together, the product should be one whole job.
                          (1/4 + 1/x)(1 5/7) = 1
The value of x is 3. Therefore, it will take 3 hours for Marna to clean the chimney alone.

Is the area of this 36 (2, 8),<br> (2, 2), (–4, 2), and (–4, 8).
almond37 [142]

Answer:

yes

Step-by-step explanation:

side 1

(2,8) to (2,2)

8-2 = 6 (length of this side)

side 2

(2,2) to (-4,2)

2-(-4) = 6

side 3

(-4,2) to (-4,8)

8-2 = 6

side 4

(-4,8) to (2,8)

2- (-4) = 6

* note: it doesn't matter the order of subtraction because length can't be negative (so just make sure your answer is positive) , also don't subtract the side that is constant, you will get 0, a side can not be 0 cm

to find the area of a square multiply length by width

6 x 6 = 36
