Step-by-step explanation:

x = price per video game

y = price per CD

164 = 5x + 3y

and then we know

x = y + 12

now we can use this as substitute in the first equation :

164 = 5(y + 12) + 3y = 5y + 60 + 3y = 8y + 60

104 = 8y

y = $13

x = y + 12 = 13 + 12 = $25

so, each CD costs $13.

Jacob and Zachary go to the movie theater and purchase refreshments for their friends. Jacob

Ok lets say
popcorn = x and
drinks = y

Jacob:      2x + 3y = 18.25
Zachary:   4x + 2y = 27.50

ok now you have to use these 2 equations to get the answer

4x + 2y = 27.50  --->   2y = 27.50 - 4x   --->  y = 13.75 - 2x

2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75             <u><em>One bag of popcorn is $5.75</em></u><em />


4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25             <u><em>One drink is $2.25</em></u><em />

I am completely lost.

The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.

So 6s^2 is the surface area. We can use this to find s.

6s^2 = 600

s^2 = 100

s = 10 cm

Aldo spends $14 each time he travels the toll roads. He started the month with $224 in his toll road account. The amount, A
skelet666 [1.2K]
Pare a.) $70 is what he would have left. Since each trip is $14 you would multiply that by the amount of times he went which was 11. 14x11 is $154. But you need what he has left so you take his total amount $224-$154 and get $70.

Part b.) 16 times. He has $224 total. You want to find out how many times he can go on the tool roads. We know the toll roads cost $14 each time. So you do $224/14 and get an even amount of 16. He would be able to use it 16 times before he have no money left.

Solve for a and x in ax^2=48<br>​
Gelneren [198K]

Answer:

ax^2 = 48\\a = \frac{48}{x^2}

ax^2 = 48\\x^2 = \frac{48}{a} \\x = \frac{\sqrt{48} }{\sqrt{a} } \\x = \frac{4\sqrt{3} }{\sqrt{a}}  \\x = \frac{4\sqrt{3a} }{a}
