7x+2

Step-by-step explanation:

add all the sides of the pentagon and make it equal to the perimeter of the square which is 4y

sides of the pentagon are

5x+3

2x+3

7x+4

9x-10

5x+8

28x+8=4y

7x+2 = y

7x+2 = answer

another way :

in a standardized test you may want to use real numbers

make x equal a prime number like 3

so then the sides are

then divide by 4

then divide by 3

which is 7 remainder of 2

which is

7x+2

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the

ExtremeBDS [4]

Step-by-step explanation:

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival

0.75 per ticket. So cost of 18 tickets= 0.75 * 18 = $13.5

Kendall spent $13.50 for tickets . Total spent = $33.50

Total spent = ticket cost + admission cost

33.50 = 13.50 + admission

Admission cost = 33.50 - 13.50 = $20

(a) y to represent the total cost , x to represent the number of ride tickets.

'b' represents the admission cost

(b) General form of linear equation is y=mx+b

m = 0.75 and b = admission cost = 20

So equation becomes y = 0.75x + 20

The value of x changes depends on the number of tickets she wants to buy.

y is the total cost she has to pay for x tickets with admission price

Answer:

V = 96 pi m^3

Step-by-step explanation:

V = (1/3) pi(r^2)h

Radius = 1/2(Diameter)

R = 1/2(12)

R = 6

Input.

V = (1/3) pi(6^2)8

Solve.

V = (1/3) pi(36)8

V = (1/3) 904.32

V = 301.44

V = 301.44/pi

V = 96 pi m^3

Cody was going to sell all of his stamp collection to buy a video game. after selling half of them he changed his mind. he then

pantera1 [17]

He now has 44 so subtract 17 from that and you get 27 (1/2 of the number of his original stamp collection). Then add 27 +27 and you get 54. I believe 54 is the answer. Hope that helps!

Isaac buys 17 anti-pollution masks for £5.25 each.

mojhsa [17]

Answer:

A) Isaac should get £ 10.75 in change.

B) The price of the e-scooter in the sale is £ 366.3.

Step-by-step explanation:

A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:

(20 x 5) - (17 x 5.25) = X

100 - 89.25 = X

10.75 = X

So Isaac should get £ 10.75 in change.

B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:

370 - (370 x 0.01) = X

370 - 3.7 = X

366.3 = X

Thus, the price of the e-scooter in the sale is £ 366.3.
