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>
You would solve, so 1162/4. Show the steps of you dividing it down on notes of paper
1 ft = 12 inches.....so 8 ft = 12* 8 = 96 inches
96 inches - 94.6 inches = 1.4 inches is cut off of each board
Answer:
C
Step-by-step explanation:
Two pyramids are similar. It means that their side lengths are proportional.
So, let's see the proportionality constant from SMALL PYRAMID to LARGE PYRAMID.
The corresponding length of 8 in small pyramid is 24 in large pyramid. We ask ourself: "8 times WHAT gives us 24?"
This is the proportionality constant (aka "k").
So, 8 times "3" is 24. So the proportionality constant is "3".
k = 3
Now, the height of small pyramid is 6 and height of large pyramid is "x". These sides will be same way proportional. So, we can say:
6 times the proportionality constant (3) would give us x
So,
6 * 3 = x
x = 18
Correct answer is C
Answer:
Step-by-step explanation:
Lets pick to columns in the table
Lets so (6,228) and (7,266)
To find the slope you need to do y1-y2/x1-x2
7-6/266-228=1/38.
1/38 is the slope.
y=1/38x+b
to find B you have to plug any of the y with the corresponding x values back in and solve for b.
Lets choose 228.
228=1/38(6)+b
228=6/28+b
(28/6)(228)=b
b=1064
the equation will be y=1/38x+1064
