Number of children that enrolled in a day care center last year = 120
Number of children that enrolled in a day care center this year = 144
Difference in the number of children = 144 - 120
= 24
Percentage of increase = (24/120) * 100
= 20 percent.
From the above deduction, we can conclude that the correct option is option "B".

1. Solve the system using substitution

Molodets [167]

X+y=8
y=3x

You would want to substitute the y for the 3x
x+3x=8

You can now add the x with the 3x to get 4x
4x=8

Now divide the 4 on both side to solve for x
x=2

Now to solve for y just substitute the x for the 2
y=3(2)

Now multiply the 3 and the 2 to solve for y.
y=6

So your corrct answer is B:(2,6)

I have to rewrite an equation so that y is a function of x. I think I'm solving for Y, because on my examples it has "y=". How d

vivado [14]

You do whatever you need to do to one side of the equation in order to have
only ' y ' left on that side, AND every time you do something to that side of
the equation, do exactly the same thing to the other side.

Here are three examples, out of the 9 answers you want handed to you:

#16: 3x + 5y = 7

Subtract 3x from each side: 5y = -3x + 7

Divide each side by 5 : y = -3/5 x + 7/5

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

#17:  13 = 12x - 2y

Add 2y to each side: 2y + 13 = 12x

Subtract 13 from each side: 2y = 12x - 13

Divide each side by 2 :  y = 6x - 13/2

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

#22: 1/4 y + 3 = -5x

Subtract 3 from each side: 1/4 y = -5x + 3

Multiply each side by 4 : y = -20x + 12
