There are 3/4 as many girls as there are boys.There are 63 students in the fifth grade. How many students are girls?

klemol [59]

Answer:

<u>27</u> students are girls.

Step-by-step explanation:

Given:

There are 3/4 as many girls as there are boys.

In the fifth grade total there are 63 students.

Now, to find the number of students that are girls.

Let the number of students that are boys be $x.$

So, the number of students that are girls = $\frac{3}{4} \ of\ x=\frac{3x}{4} .$

Total number of students = 63.

Now, to get the number of students that are girls we solve an equation:

$x+\frac{3x}{4} =63\\\\\frac{4x+3x}{4} =63\\\\\frac{7x}{4} =63\\\\Multiplying\ both\ sides\ by\ 4\ we\ get:\\\\7x=252\\\\Dividing\ both\ sides\ by\ 7\ we\ get:\\\\x=36.$

Now, substituting the value of $x$ :

$\frac{3x}{4} \\\\=\frac{3\times 36}{4} \\\\=\frac{108}{4} \\\\=27.$

Therefore, 27 students are girls.

What is the slope of the line represented by 3x - 7y = 28?

olya-2409 [2.1K]

Answer: 3/7

Why?
Reorganize the equation 3x-7y=28 you get
Y=3/7x-4
Because y=mx+b and m=the slope this shows that the slope is 3/7

Hope this helps :D

Answer:

C. Slope is 2

Step-by-step explanation:

Since this equation is written in the y=mx+b equation, 2 would be the slope, because any number that comes before x (AKA "m") is always the slope. For example, if you were trying to find the slope for the equation y=4x+19, 4 would be the slope.
