Simplifying

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

Reorder the terms:

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

3m = (3 * 5 + m * 5) + -3

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

Reorder the terms:

3m = 15 + -3 + 5m

Combine like terms: 15 + -3 = 12

3m = 12 + 5m

Solving

3m = 12 + 5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-5m' to each side of the equation.

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

Combine like terms: 3m + -5m = -2m

-2m = 12 + 5m + -5m

Combine like terms: 5m + -5m = 0

-2m = 12 + 0

-2m = 12

Divide each side by '-2'.

m = -6

Simplifying

m = -6

Answer:

m = -6

Step-by-step explanation:

First you distribute 5 into (m+3) so it would 5m + 15

The equation now would be:

3m = 5m + 15 - 3

3m = 5m + 12

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

-2m = 12

-2m/-2 = 12/-2

m = -6

Answer:

y=-1/2x-3

Step-by-step explanation:

Let's pick two points for slope.

$\frac{-1+3}{-4-0}$

$\frac{2}{-4}$

For the y-inctercept, the line intersect at the y-axis at (0,-3)

CHECK:

$y=-\frac{1}{2} (-4)-3$

$y=2-3$

$y=-1$

help im stuck pls -- Refer to the table above. Determine the percent of all voters that did not vote Republican or Democrat but

dsp73

Answer:

9.9%

Step-by-step explanation:

Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

$\frac{222}{2222} =0.09999...\\$

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

9.9%, which could be rounded to 10% or 9%.

The probability that the number on the card is a perfect square is

amid [387]

From 2 to 101 , the perfect square numbers are ,

4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .

Total number of possible outcomes = 100.

Total number of favourable outcomes = 9 .

Hence ,

→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>
