42 = y + 15 whats y? y == __
Solution
[tex]y=27[/tex]
Step-by-step explanation:
Subtract [tex]15[/tex] from both sides of the equation:
[tex]42=y+15[/tex]
[tex]42[/tex][tex]-15=y+15[/tex][tex]-15[/tex]
Simplify:
Subtract the numbers:[tex]42-15=y+15-15[/tex]
[tex]27=y+15-15[/tex]
Subtract the numbers:[tex]27=y+15[/tex][tex]-15[/tex]
[tex]27=y[/tex]
Move the variable to the left:[tex]27=y[/tex]
[tex]y=27[/tex]
[tex]y=27[/tex]

12 = 3(m - 17)
Help please. You have to use distributive property to solve.
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)

Kieran picks a bead out of a bag without looking.He records the colour and replaces the bead.Kieran does this 50 times.He picks out a red bead 15 times. Estimate the probability of picking a red bead.
Answer: 3/10
Step-by-step explanation:
From the question, we are informed that Kieran picks a bead out of a bag without looking and that he records the colour and replaces the bead.
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:
= 15/50
= 3/10

Find the slope !!!
40 points
Answer:
C
Step-by-step explanation:
Answer:
C. m = -1/4
Step-by-step explanation:
You must find two different numbers on the number like. I will use (0, 1) and (4,0)
0-1/4-0
Combine
-1/4
m = -.25
The answer to the problem
================================================
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.

Help plzzzz.................
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
