Let us assume the regular price of each tube of paint = r.
0.50 off each tube.
New price of each tube = r - 0.50.
She buy 6 tubes.
Total price of 6 tubes = 6×(r-0.50).
We are given total price = $84.30 .
Therefore, we can setup an equation
6×(r-0.50) = 84.30.
Distributing 6 over (r-0.50), we get
6r - 3.0 = 84.30
Adding 3.0 on both sides, we get
6r - 3.0+3.0 = 84.30+3.0
6r = 87.30
Dividing both sides by 6, we get
6r/6 = 87.30/6
r = 14.55
<h3>Therefore, required equation is
6(r-0.50) = 84.30 and the regular price of each tube of paint is $14.55.</h3>

Step-by-step explanation:
All you have to do here is replace f(x) with x + 2 and h(x) with 1/x-1.
It's like plugging in a number for x, but instead you are plugging in a whole function instead of just a number. Whenever you are pluging something in, whatever it is, make sure it is in parentheses: ( ) always!
Until your understanding of algebra becomes stronger.
2f(x)-hx
First lets plug in x + 2 for f(x). It's gonna look like this:
2(x + 2) - h(x)
Notice how I put x + 2 in parentheses next to the 2, you
a l w a y s want to do this. Now we just do the same for h(x):
2(x + 2) - (1/x - 1)
And that's it. That's all you have to do.
Answer:
- C. π(3in)2(12in) − 9(four over threeπ(1.5in)3)
Step-by-step explanation:
Volume of water is the difference of volume of vase at 12 in height and the total volume of marbles.
<u>Volume of cylinder up to water level:</u>
- Vs = πr²h = π(6/2)²(12) = π×(3 in)²×(12 in)
<u>Volume of marbles:</u>
- Vm = 9(4/3πr³) = 9×(4/3×π(3/2)³) = 9×(4/3×π×(1.5 in)³)
<u>Volume of water:</u>
- Vw = Vs - Vm = π×(3 in)²×(12 in) - 9×(4/3×π×(1.5 in)³)
Correct choice is C
