multiply by 8 on both sides
(20)8 - 8(4b/8) = (18)8
160 - 4b = 144
subtract 160 on both sides
160 - 160 - 4b = 144 - 160
-4b = -16
divide by -4 on both sides
-4b/-4 = -16/-4
b = 4
A cell phone company charges a flat rate of $2.50 per month, with an additional charge of $0.15 per minute. How many minutes did Laura talk on her cell phone if her monthly bill was $72.25?
Answer:
465 minutes
Step-by-step explanation:
First things first, you have to make an equation! It would be...
2.50+0.15m=72.25
Keep in mind that m stands for minutes.
Now let's solve it!!
First let's subtract 2.50 from both sides.
0.15m=69.75
Now, let's divide 0.15 on both sides!
m= 465
465 minutes!!
Hope this helped!! :D

y = 2x
x + y = -6
Answer:
y=-4
x=-2
Step-by-step explanation:
Given:
x+y=-6
y=2x
So, you can then substitute y for 2x
x+(2x)=-6
Then, solve for x
3x=-6
x=-2
Then solve for y
y=2x=2(-2)=-4

Venetta buys 2 pounds of pistachios and 3 pounds of almonds.
The pistachios cost $4 more per pound than the almonds. She
pays a total of $48. Select all the correct statements about this
situation.
Reducing the number of pounds of almonds by one results in a
total cost of $40.
The pistachios cost twice as much per pound as the almonds.
The cost p. in dollars, of 1 pound of pistachios is modeled as 2p +
310 - 4) = 48.
One pound of pistachios plus 1 pound of almonds cost $20.
The cost a, in dollars, of 1 pound of almonds is modeled as 2la – 4)
+ 3a = 48
Answer:
Step-by-step explanation:
I cant fully answer it, I'm having trouble with too. But i know for a fact that the cost of a pound of pistachios is 12 dollars. The cost of a pound of almonds is 8 dollars. Sorry -_-
What is the volume of a cylinder with a base radius of 7in. and a height of 12in?
Answer:
1847.26 cubic inches
Step-by-step explanation:
The volume of a cylinder is given by the formula:
V = Ah
Where V is the volume of the cylinder, A is the area of the base, and h is the height of the cylinder. The area of the base can be shown as the formula for the area of a circle:
A = πr²
Where r is the radius of the circle.
Now, find the area of the base of the cylinder:
A = π(7)²
A = 153.93804
Next, plug this value into the equation for volume, substituting h for the height of the cylinder; 12 inches.
V = 153.93804(12)
V = 1847.26
Volume is given in cubic units, and the units for this cylinder are inches, so this cylinder has the following volume:
1847.26 cubic inches
HELP
Vaughn is calculating the volume of the cylinder below using the following work.
51 cm
24 cm
V = 3.14(12)(5)
= 3.14(144) (5)
= 2,260.8 cm
What was Vaughn's first error?
He confused the height and the diameter.
He squared 12 instead of 24.
He applied the exponent before multiplying 12 and
5.
He used the wrong units in his final answer.
Answer:
He confused the height and diameter
Step-by-step explanation:
Given that,
The radius of the cylinder, r = 2.5 cm
Height of the cylinder, h = 24 cm
The volume of the cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\=3.14\times (2.5)^2\times 24\\\\=471\ cm^3[/tex]
Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).
In Terry's hometown, the probability of snow on Saturday is approximately 0.07. Which of the following
best describes the chances of snow on Saturday in Terry's hometown?
O A. likely
O
B. certain
his
O
C. unlikely
D. impossible
Answer:
c
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability it would snow is 0.07 or 7%. this is quite low. so, it is unlikely that it would snow

Find mAC. Will give brainliest
Answer:
58° = measure of arc AC
Step-by-step explanation:
The measure of an angle formed by 2 chords is equal to 1/2 the sum of the measures of the intercepted arcs.
65 = (measure of arc AC + measure of arc BD)/2
= (measure of arc AC + 72)/2
130 = measure of arc AC + 72
58° = measure of arc AC

What is the distance between two points(2,-6)(-7,1)
Answer:
11.4
Step-by-step explanation:
Find the distance in the x-direction between the x-components: 2 - (-7) = 9.
Similarly: between the y-components: 1 - (-6) = 7
Apply the Pythagorean Theorem: 9^2 + 7^2 = d^2, where d is the desired distance:
81 + 49 = d^2, or d^2 = 130
The distance d is approximately √130 ≈ 11.4
Answer:
Square root of 130
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]
[tex](x_{1}, y_{1} )[/tex] is your first set of coordinates : (2, -6)
[tex](x_{2}, y_{2} )[/tex]is your second set of coordinates : (-7, 1)
