8y-2x=24
Solve for y
8y=2x+24
y=(1/4)x+3
So no it is in the form y=mx + c
m is the slope
So the slope is 1/4

Dear Madison,

I will be glad to offer you my services. In order to find the slope of an equation you must use the slope intercept formula. Here is the formula:

y=mx+b

Your equation is actually almost in slope form, however there is an 8 attached to the "y." When you have a number and a letter side by side it means that they are being multiplied. So for example:
"10C" actually means "10 multiplied by C"
If you are familiar with how equations work, then you can proceed from here. If not I will explain here. Equations are like see-saws, you want them to be balanced. So whatever you do to one side has to be done to the other. In order to balance them you have to do the opposite function of what you are trying to change. So if you are trying to get rid of a positive 8 you would subtract.
The Work to Solve Your Equation:
1. Here is the equation: 8y-2x=24
2. Divide 8y by 8 to leave y-2x on the left side of your equation.
3. Now remember whatever you do to one side has to be done to the other. So you must divide 24 by 8.
4. Now this is what you have: y-2x=3
5. The formula is "y=mx+b" so we now have to rearrange our numbers into that format. So we want to have the y by itself. In that case we would add a positive 2x in order to remove the "-2x".
6. y=2x+3
7. I sincerely hope that this explanation was useful.

Explain how the statement "there is 3/4 cup per serving" represents a rate.

Aleonysh [2.5K]

There is 3/4 cup of whatever in one serving. If that serving amount changed to 2, then the 3/4 would be multiplied by 2. If there is half a serving, then it would be divided by 2. There is a constant change, and not one that is always changing.

An electronic store prices 3 dozen video games at a total of 1467 if each video game costs the same amount what m is the total c

PilotLPTM [1.2K]

Answer:4 dozens of video games would cost $1956

Step-by-step explanation:

An electronic store prices 3 dozen video games at a total of 1467. A dozen of video games is 12. Therefore, the total number of video games whose cost is 1467 is 12 × 3 = 36

if each video game costs the same amount, then the cost of one video game would be

1467/36 = $40.75

The total number of video games in 4 dozens of video game would be

4 × 12 = 48

Therefore, the total cost of 48 video games would be

48 × 40.75 = $1956

Rachel has 60 scones. She sells them to Robbie, Cameron, Louis, Tom and

Nutka1998 [239]

We can start by writing all that we know about the problem. Let us write down how many scones each boy has:
$R_{o} : x$
$C_{a} : x+k$
$L_{o} : x+2k$
$T_{o} : x+3k$
$C_{h} : x+4k$
Note that k is the increase, we know it's a constant. This is not a system of equations, please keep that in mind. We will use rest of the information given to build the system. We have two variables x (the number of cookies the first boy bought) and k( the increase), that means we need to have two equations to solve this problem.
We know that total amount of scones is 60, so we can use that information to build our first equation. We sum all of the scones and we get 60.
$R_{o}+C_{a}+L_{o}+T_{o}+C_{h}=60$
$5x+10k=60$
We know that Robbie and Cameron combined have 3/7 of <span>Louis, Tom and Charlie combined. We can use this information to build our second equation.
</span> $R_o+C_a= \frac{3}{7} (L_o+T_o+C_h)$
$2x+k= \frac{3}{7} (x+2k+x+3k+x+4k)$
$2x+k= \frac{3}{7} (3x+9k)$
$14x+7k=9x+27k$
$5x=20k$
$x=4k$
Now this piece of information alows us to solve the first equation that we made and this will solve our problem. We simply plug in x=4k into 5x+10k=60.
$5(4k)+10k=60$
$30k=60$
$k=2$
Now we can plug this information into the same equation 5x+10k=60 and get x.
$5x+10(2)=60$
$5x=40$
$x=8$
And that's it. Now we can write out how many cookies each boy has bought.
$R_{o} : x=8$
$C_{a} : x+k=10$
$L_{o} : x+2k=12$
$T_{o} : x+3k=14$
$C_{h} : x+4k=16$
If you add them all up you get 60.
