During first semester the ratio of the number of students in art class to the number of students in gym class was 2:7. However t

he art classes were really small and the gym classes were large so the principal changed students classes for second semester. In second semester the ratio of the number of students in art class to the number of students in gym class was 5:4. If 75 students were in art class second semester how many were in art class and gym first semester

5/4 = 75/g....cross multiply because this is a proportion
5g = 300
g = 300/5
g = 60
so in 2nd semester, there were 75 students in art class and 60 students in gym class....for a total of 135 students.

1st semester....ratio was 2:7...added = 9
art : 2/9(135) = 270/9 = 30 <=== art class had 30
gym: 7/9(135) = 945/9 = 105 <=== gym class had 105

What is the solution to the system of equations?<br><br> y = –5x + 3<br><br> y = 1
Alinara [238K]
Ok so we know that y=1 so we can simply sub in the value of y into the equation :

y = -5x +3

1 = -5x +3

Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.

5x = 3 - 1

5x = 2

x = 2/5

x = 0.4

Hope this helps :).

GO.o has 3 orange picks for every 2 green. If there are 25 picks in all, how many picks are orange?
Reika [66]

Given

GO.o has  3 orange picks for every 2 green

there are 25 picks in all

Find out how many picks are orange.

To proof

As given in question

GO.o has  3 orange picks for every 2 green

i.e the ratio of orange to every green becomes

\frac{Orange}{Green}:\frac{3}{2}

total number of picks = 25

let the GO.o pick of  3 orange picks for every 2 green =x

than the equation becomes

3x + 2x = 25

5x = 25

x = 5

Than

the number of oranges = 3x

putting the value  of x

                                     = 15

the number of green = 2x

                                  =  10

thus the 15 picks are orange.

Hence proved

NeTakaya

Answer:

The length of each side of square is <u>5ft</u>.

Step-by-step explanation:

Given:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.

Now, to find the length of each side of square.

Now, we need to get the area of the square first:

<u>Area of combined figure - area of triangle = area of square.</u>

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

25 =a^{2}

<em>Using square root both sides we get:</em>

5=a

<em>So, the side = 5 ft.</em>

Therefore, the length of each side of square is 5ft.
