The answer is a............
17.5x12=210
210 divided by 14=15
15x2.50=37.5
37.5
17.5 is feet so you need to divide by 12 for inches which gets 210 and you need each necklace to be 14 inches so you need to divide 210 by 14 which is 15 each necklace costs 2.50 so you multiply 2.50x15
You get 37.5
The two containers hold 328 ounces at the they hold same amount of water.
<u>Step-by-step explanation:</u>
The equations below model the ounces of water, y, in each container after x minutes.


At the time after the start when the containers hold the same amount of water, the two equations must be equal.
⇒
The first step is to divide everything by 2 to make it simplified.
⇒ 
Now put everything on the left
.

Add the like terms together to further reduce the equation

Factorizing the equation to find the roots of the equation.
Here, b = -12 and c = -28
where,
- b is the sum of the roots ⇒ -14 + 2 = -12
- c is the product of the roots ⇒ -14 × 2 = -28
- Therefore, (x-14) (x+2) = 0
- The solution is x = -2 or x = 14
Take x = 14 and substitute in any of the given two equations,
⇒ 
⇒ 
⇒ 328 ounces
∴ The two containers hold 328 ounces at the they hold same amount of water.
Answer: 7
Step-by-step explanation:
C = 9
B = 6
Wherever you see a c, you put a 9. Wherever you see a b, you put a 6. If there is already a number in front of the B, multiply it by 6
Lia=L
Phil=12.80+L
Cam=3L
L+12.80+L+3L=200.30
5L+12.80=200.30
5L=200.30-12.80
5L=187.5
L=187.5/5
Plug into the equations at the top
L=Lia=$37.5
Phil=12.80+37.5=$50.30
Cam=3(37.5)=$112.50
