Step 1 is wrong, because when you distribute 5(x-1) it will equal 5x-5

5m -2(m + 2) = -(3m +15)

Nostrana [21]

Answer:

m = -11/6

Step-by-step explanation:

5m -2(m + 2) = -(3m +15)

5m - 2m - 4 = -3m - 15

3m + 3m = -15 + 4

6m = -11

m = -11/6

744 Carnations. 12 of these go into a bunch.

1896 roses, 24 go into a bunch.

744/12=62

1896/24=79

62 bunches of carnations and 79 bunches of roses.

Solve the system -10=-2y+x 6y=3x+11

belka [17]

Answer: No Solutions exist

Step-by-step explanation:

We have the following system of equations

$-10=-2y+x$

$6y=3x+11$

Rewriting the second equation we have:

$-11=-6y+3x$

Now we multiply the first equation by -3 and add it to the second equation

$30=6y-3x$

$-11=-6y+3x$

---------------------------------

$19=0$

Equality is not satisfied. Then the system has no solution

What do I need to subtract from to get angle two?

ololo11 [35]

Step 1) Add up the three given angles: 125+109+83 = 317

Step 2) Subtract the result (found in step one) from 360
360 - 317 = 43

The reason for the 360 is because for any four-sided polygon, the angles always add up to 360 degrees.

The answer is 43
