You are ordering pizzas for a birthday party and getting them delivered to your house. You order 12 pepperoni pizzas, 8 cheese p

krok68 [10]

Let

x-------> the cost of each pepperoni pizza

y-------> the cost of each cheese pizza

z-------> the cost of each Hawaiian pizza

we know that

$12x+8y+4z+5.50=184.54$ ------> equation A

$y=x$ -----> equation B

$z=x$ -----> equation C

Substitute equation B and equation C in equation A

$12x+8x+4x+5.50=184.54$

solve for x

$24x=184.54-5.50$

$x=179/24$

$x=\$7.46$

therefore

<u>the answer is</u>

$\$7.46$

1. Pilar and her sister Marisol live near the beach. Pilar has 80 seashells in her collection when Marisol started collecting se

enot [183]

Answer:

a. 20x > 10x + 80

b. •20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10: 10x/10 > 80/10

• Simplify: x > 8

Step-by-step explanation:

10x + 80 = number of seashells Pilar has.

20x = number of seashells Marisol has.

answer for a: 20x > 10x + 80

answer for b: 20x > 10x + 80

• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x

• Simplify: 10x > 80

• Divide both sides by 10: 10x/10 > 80/10

• Simplify: x > 8

Leo, Kush and Mai share some money in the ratio 3:5:8

Marta_Voda [28]

Answer:

The total amount of money that they shared is $\£6,000$

Step-by-step explanation:

Let

x-----> amount of money Leo shares

y-----> amount of money Kush shares

z-----> amount of money Mai shares

we know that

$\frac{x}{y} =\frac{3}{5}$

$x=\frac{3}{5}y$ -----> equation A

$\frac{y}{z} =\frac{5}{8}$

$z=\frac{8}{5}y$ -----> equation B

$\frac{x}{z} =\frac{3}{8}$

$z=\frac{8}{3}x$ -----> equation C

$y=x+750$ ------> equation D

substitute equation A in equation D and solve for y

$y=\frac{3}{5}y+750$

$y-\frac{3}{5}y=750$

$\frac{2}{5}y=750$

$y=750*5/2=\£1,875$

Find the value of x (equation A)

$x=\frac{3}{5}(1,875)=\£1,125$

Find the value of z (equation C)

$z=\frac{8}{3}(1,125)=\£3,000$

therefore

The total amount of money is equal to

$x+y+z=\£1,125+\£1,875+\£3,000=\£6,000$

Gennadij [26K]

Since the steps are the same size, and she ended up where she started, she must have taken the same number of steps forward as she took backward.

16/2 = 8

She took 8 steps forward and 8 steps backward.

A television weighs 50 pounds and a microwave

Ilia_Sergeevich [38]

Answer:

Step-50*t + 30*m = 1500, (1) (pounds)

4*t + 3*m = 138. (2) (cubic feet)

From (2), express 3m = 138 - 4t, and substitute it into (1). You will get

50t + 10*(138-4t) = 1500, or

10t = 1500 - 1380 ---> 10t = 1120 ---> t = 112 TVs.

From this point, find the number of microwaves on your own.
