A theater charges $5.00 admission for adults and $2.50 for children. At one showing 240 admissions brought a total of $800. How

SOVA2 [1]

Answer:

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

This means that the money paid by adults and kids is $5 multiplied by x (5x) and $2.50 multiplied by y (2.5y)

This will give two equations as shown below

x + y = 240 total admissions......................... equation 1

5x + 2.5y = 800 total money paid..................equation 2

Making x the subject of formula in equation 1

x=240-y......................................................equation 3

Substituting equation 3 into equation 2

5(240-y) + 2.5y = 800 removing the brackets

1200 - 5y + 2.5y = 800 grouping like terms

-5y + 2.5y = 800-1200 simplifying

-2.5y = -400 therefore

-2.5y/-2.5 = -400/-2.5

y = 160

Substituting y into equation 3

x = 240 - y

x = 240 - 160

x = 80

Hence number of adults who attended = 80

Solve the equation x² = 5. (must show equality properties in work so I can earn full credit)

X² = 5
take root to both side to clear the square

√x² = ±√5

X = ±√5

The Darnells are having a swimming pool installed. The pool has a radius of 14 feet and a height of 4 feet. What is the volume o

ella [17]

So a circular pool will be in the shape of a cylinder. and the formula for finding the area of a cylinder is $2 \pi r^{2} +2 \pi rh$ . r=radius, h=height. If we put the numbers into the equation it is $2 \pi 14^{2} +2 \pi 14(4).$ .14 squared is 196 and 4*14= 56. So our equation is now $2 \pi (196)+2 \pi (56)$ . 2*pi=6.28318530718 but let's round that to 6.283. So now our equation is much simpler 6.283(196)+6.283(56). Just multiply them. 1231.504+351.858= 1583.362 is your final answer.

Solve?? 3x + 10 > 4

Artemon [7]

Answer:

x>−2

Step-by-step explanation:

1 Subtract 1010 from both sides.

3x>4-103x>4−10

2 Simplify 4-104−10 to -6−6.

3x>-63x>−6

3 Divide both sides by 33.

x>-\frac{6}{3}x>−

4 Simplify \frac{6}{3}

to 22.

x>-2x>−2
