Under her cell phone plan, Katherine pays a flat cost of $50 per month and
$5 per gigabyte. She wants to keep her bill at $71 per month. How many
gigabytes of data can she use while staying within her budget?
Answer: x = 4.2
Step-by-step explanation:
To keep her bill at $71 per month, she needs to consume 4.2 gigabyte in a month.
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the initial value of y.
Let y represent the amount of money paid for x gigabyte.
Given a flat cost of $50 per month and $5 per gigabyte, hence m = 5, b = 50. Therefore:
y = 5x + 50
For a bill of $71 per month:
71 = 5x + 50
5x = 21
x = 4.2
To keep her bill at $71 per month, she needs to consume 4.2 gigabyte in a month.

Jacks Plumbing charges customers $100 per hour for repair jobs. Al's Plumbing charges according to the equation y = 75x + 50, where x = time in hours and y = cost
dollars
Explain why Ars Plumbing charges less than Jacks Plumbing for a 4-hour repair job.
Does Als Plumbing charge less than Jacks Plumbing for all repair jobs? Explain why or why not.
Answer:
As given,
Per hour cost of Jack's plumbing = $100
Also,
Al's plumbing charges = 75x + 50 where x = time in hours .
Now,
Al's plumbing cost for 4 hours:
Here , x = 4
⇒75x + 5 = 75(4) + 50 = 300 + 50 = 350
∴ we get
Al's plumbing cost for 4 hours = $350
Now,
As Jack cost for 1 hour = $ 100
⇒ For 4 hour = 4×$100 = $400
∴ we get
Jack's plumbing cost for 4 hours = $400
As we can see that
$ 400 > $350
⇒Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
Now,
Al's plumbing charges = 75x + 50 where x = time in hours .
For 1 hour
75x + 50 = 75(1) + 50 = 125
Al's 1 hour cost = $125
whereas Jack Plumbing cost for 1 hour = $100
∴ we get
$125 > $100
⇒Al's 1 hour cost > Jack's 1 hour cost
Now,
Al's 2 hour cost
75x + 50 = 75(2) + 50 = 150 + 50 = 200
Al's 1 hour cost = $200
whereas Jack Plumbing cost for 2 hour = $200
∴ we get
$200 = $100
⇒Al's 2 hour cost = Jack's 2 hour cost
Now,
Al's 3 hour cost
75x + 50 = 75(3) + 50 = 225 + 50 = 275
Al's 1 hour cost = $275
whereas Jack Plumbing cost for 3 hour = $300
∴ we get
$275 < $300
⇒Al's 3 hour cost < Jack's 3 hour cost
Als0,
Jack's plumbing cost for 4 hours > Al's plumbing cost for 4 hours
∴ we get
We can not say that Als Plumbing charge less than Jacks Plumbing for all repair jobs.
Because the charge is fluctuating ,
For 1 hour , Aly' charge is grater whereas The 2 hour cost of Jack's is higher.
So, the Correct answer is - No, Al's Plumbing charge is not always less than Jacks Plumbing for all repair jobs.

Mr. Tanner bought some boxes of markers with 18 markers in each box. He kept 2 markers and gave the rest to his students. Use the equation below to calculate the number of boxes (b) he bought. 18b – 2 = 214
Answer: 18b-2+2=214 +2
Step-by-step explanation:Add 2 both sides of the equation
Answer:
b = 12; he bought 12 boxes.
Step-by-step explanation:
18b - 2 = 214 (subtract 2 on both sides)
18b = 216 ( divide 18 on both sides to get 'b' alone)
b = 12

i cant give u the answer but here is an example hope this helps slope = "rise over run" the difference in y values divided by the difference in x values
= 6/-3 = -2 = m. It's negative because as x increases, y decreases
plug that into the point slope formula, with either point. generally use the most simple point
y-h= m(x-k) where m= -2 and (k,h) = (2,-2)
y+2 = -2(x-2)

solve the inequality 2(n+3) - 4 < 6. then graph the solution.
Please help ??
Answer:
n < 2
Step-by-step explanation:
Answer: Look at the explanation please.
Step-by-step explanation:
The first thing you would do is distribute the 2 to the n and the 3.
You will then get 2n+6-4<6
Next, you will have to subtract 6-4 and you will get 2
You will the have 2n+2<6
Subtract 2 from 2 to get 0 and from 6 to get 4.
Your left with 2n<4
Then, divide 2 from 2n and 2 from 4
Last, your answer will be n<2.
Graphing
Your graph would look like (from what I see in my book)
You have seven tick marks and in the middle will be 0.
From the left of 0 should have negative 1, 2, and 3
From the right of 0 would be positive 1, 2, and 3
On the top of 2 would be a open circle and an arrow going to the left.
Hope this helps :)
The time of a pendulum varies as the square root of its length. If the length if a pendulum which beats 15seconds is 9cm, find the length that beats 80seconds and the time of a pendulum with length 36cm
Answer:
length= 3.7 ft.
Step-by-step explanation:
T= (square root of length) * k
1.8 seconds = (square root of 3) * k
k= 1.8 seconds / (square root of 3)
a.) T= (square root of 11) k
substituting k:
T=(square root of 11) * 1.8 seconds / (square of 3)
T= 3.4 seconds
b.) 2 seconds = (square root of length) k
substituting k:
2 seconds =(square root of length) 1.8 seconds / (square root of 3)
Divide the equation by 1.8 seconds / (square root of 3):
2 seconds / [1.8 seconds / (square root of 3)] = (square root of length)
10(square root of 3) / 9 = (square root of length)
square both sides:
100/7 ft= length
length= 3.7 ft.
Hope this helps.

A box of cereal states that there are 87 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 3 cups of the cereal?
Answer:
3 cups = 348 calories
Step-by-step explanation:
Step 1
Let the calories in one cup be represented as C
Therefore
3/4 x C = 87 calories
C = 87 X 4 / 3 = 116
unit rate is 116 calories per cup.
Step 2- Solving the number of calories in 2 cups
1 cup serving = 116 calories
2 cups servings = 116 x 2= 232 calories
116 x 3 = 348 calories

Answer:
25-7
Step-by-step explanation:
"Substitute for": Replace x with ____
Since it is given that x = 25 -y, we can replace the x in 5x + y = 10 with 25 - y by the substitution property of equality.
Answer:
The expression to substitute for x is: 25-y, as said in the first equation
Step-by-step explanation:
Not sure if you need to solve for the variables, but here:
To find y:
Put 25-y in place of x.
You will get:
5(25-y) + y = 10
Use the Distributive Property and multiply 25 and y by 5:
125 - 5y + y = 10
Combine like terms (the y's):
125 - 4y = 10
Put like terms on the same side (move the 125 to the right side of the equal sign by subtracting 125 from both sides:
-4y = -115
Divide both sides by -4:
y = 28.75 (or 28-3/4)
To find x:
Substitute 28.75 for y in either equation.
First equation:
x= 25 - 28.75
x= -3.75
Second equation:
5x + 28.75 = 10
Subtract 28.75 from both sides:
5x = -18.75
Divide both sides by 5:
x = -3.75
