12 = 3(m - 17)

Help please. You have to use distributive property to solve.

Answers

Answer:

m = 21

Step-by-step explanation:

12 = 3(m - 17)

12 = 3m - 51 (Found using the distributive property)

63 = 3m (Found by adding 51 to both sides)

21 = m (Found by dividing both sides by 3)

He does this 50 times and he picks out a red bead 15 times. The probability of picking a red bead will be the number of times a red bead was picked divided by the number of title times a bead was picked. This will be:

The answer to the problem

Answers

Answer:  -2/3

================================================

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (8-6)/(2-5)

m = (2)/(-3)

m = -2/3

As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.

The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.

Answer:

a = 6, b = - 12

Step-by-step explanation:

Expand the left side and compare the coefficients of like terms to those on the right side.

a(4x - 10) ← distribute parenthesis

= 4ax - 10a

Compare to 24x + 5b , then

4a = 24 ( divide both sides by 4 )

a = 6

Then

5b = - 10a = - 10(6) = - 60 ( divide both sides by 5 )

b = - 12
