Solve the system by substitution 10x=y 2x+y=-24

Answer: x=-2

Y= -20

Step-by-step explanation

You replace the y in the second equation with 10x. This is because it says 10x=y

2x+10x=12x so you put that

12x=-24

To get x by its self you divide by 12.

-24 divided by 12 is -2.

Now you plug in -2 to either equation as y. I chose the first one because it's easier.

10(-2)=y

-20=y

Write the raito as a fraction simplest from 12 boys and 15 girls​
kiruha [24]

Step-by-step explanation: We can write a ratio using the word "to", using a colon, or using a fraction bar.

Here, since we want our ratio in simplest form,

I would use a fraction bar.

Now, the problem asks us to compare

the number of boys to the number of girls.

We know that there are 12 boys

and we know that there are 15 girls.

So our ratio is 12/15.

However, this can be reduced to 4/5.

8 times the difference between a number and 6 is equal to 4 times the number.
iVinArrow [24]
8(x - 6) = 4x
Distribute.
8x - 48 = 4x
Subtract 8x from both sides.
8x -8x - 48 =4x -8x
Now you have...
-48 = -4x
Divide -4 by both sides.
-48/-4 = -4x/-4
12 = x
The number is 12.
