a). Square

b). Rectangle

c). Triangle

Step-by-step explanation:

Given: A solid cube dough.

To find: Shape of Cross sections.

a). when a slice through the center and parallel to a side.

In this way the cube is cut into half down the middle parallel to the side and we will get a square cross section.

b). when a slice that cuts through the left top edge and the right bottom edge.

In this way we cut the cube from one edge to the other edge, we get a rectangle.

c). when a slice that cuts across a corner through three sides of the cube.

It cut the cube through three sides, and we get a 3 sided cross section.i.e,a triangle.

Answer:

Step-by-step explanation:

x-y=14

x-1/3y=1/10

-y=14-x

y=-14+x

take out the factors

x-10/30y=3/30

30x-10y=3

substitute

30x-10(-14+x)=3

30x+140-10x=3-140

20x/20=-137/20

x=-6.85

y=-14+(-6.85)

y=-20.85

Question is Incomplete;Complete question is given below.

Mustafa’s soccer team is planning a school dance as a fundraiser. The DJ charges $200 and decorations cost $100. The team decides to charge each student $5.00 to attend the dance. If n represents the number of students attending the dance, which equation can be used to find the number of students needed to make $1,500 in profit?

$5n - 300 = 1,500\\\\5n + 300 = 1,500\\ \\5n - 200 + 100n = 1,500\\\\5n - 100 -200n = 1,500$

Answer:

$5n - 300 = 1,500$

Step-by-step explanation:

Given:

Charges of DJ = $200

Decoration charges = $100

Profit need to be made = $1500

Charges per student to attend the dance = $5

We need to write the equation to find the number of students for to attend the dance in order to make profit.

Solution:

Let the number of student be represented by 'n'.

Now we can say that;

Profit to be made should be equal to Charges per student to attend the dance multiplied by number of students minus sum of Charges of DJ and Decoration charges.

framing in equation form we get;

$5n-(200+100)=1500\\\\5n-300=1500$
