We would just take the average of 15% and 20% which would be 17.5% and we could round up to 18% so 18% of 111.8 is 20.124 and if you add them together you would get 131.9 and that rounds up to 132 tiles.

It costs $20.50 to enter an amusement park and $0.25 to ride a ride. You have $21.50. Write an equation that represents the numb

Mrac [35]

Answer:

4 rides

Step-by-step explanation:

Total amount = $21.50

Entry charge = $20.50

Amount left = $21.50 - 20.50 = $1

Number of rides

$r = \frac{1}{0.25} = \frac{100}{25} = 4 \\$

Another way:

$0.25\:r + 20.50 = 21.50\\0.25\:r = 21.50 - 20.50\\0.25\:r = 1\\r = \frac{1}{0.25}\\r = \frac{100}{25}\\r = 4\\$

1. r=n/3(b+k) solve for k 2.c=7.09 pie=3.4 solve for 2pieR^2

saul85 [17]

R = n/3 (b + k)
3r = n(b + k)
b + k = 3r/n
k = 3r/n - b

Find the value of x and y. WILL MARK BRAINLIEST

Eduardwww [97]

Answer:

x=7

y = 4

Step-by-step explanation:

Since it is a parallelogram

2x-2 =12

and 2y =8

2x-2=12

Add 2 to each side

2x-2+2 =12+2

2x = 14

Divide by 2

2x/2 =14/2

x = 7

2y =8

Divide by 2

2y/2 =8/2

y =4
