Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10

A cell phone company charges $4 per GB beyond 20GB in a month. The monthly plan is $59.99, and the bill for January is $75.99. How many GB were used in that month?
Answers
Answer:
24GB
Step-by-step explanation:
75.99-59.99=16 This is how much extra money was paid.
16/4=4 Divide this by the cost per GB.
20+4=24GB Add the 20GB included in the plan.
Answer:
Step-by-step explanation:
75.99-59.99=16
$16 worth of GB used for that month
which means 16/4=4 GB extra were used that month beyond the 20 GB
so total GB usage for that month is 24 GB

A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on, until there are 200 logs in the bottom row. Is the pattern an arithmetic sequence? Identify a and d. Write the 50th term of the sequence. Find the total number of logs in the first 10 rows.
Answers
Answer:
1) Is the pattern an arithmetic sequence?
Yes it is
2)Identify a and d.
a = First term = 2
d = Common difference = 2
3) Write the 50th term of the sequence.
50th term = 100
4) Find the total number of logs in the first 10 rows.
= 1010 logs
Step-by-step explanation:
Is the pattern an arithmetic sequence?
Yes it is
2) Identify a and d.
A pyramid of logs has 2 logs in the top row, 4 logs in the second row from the top, 6 logs in the third row from the top, and so on,
The formula for arithmetic sequence =
an = a+ (n - 1)d
a = First term
d = Common difference
For the above question:
a = 2
d = Second term - First term
= 4 - 2
d = 2
3) Write the 50th term of the sequence.
Using the formula for arithmetic sequence
an = a+ (n - 1)d
a = 2
n = 50
d = 2
a50 = 2 + (50 - 1)2
= 2 + (49)2
= 2 + 98
= 100
The 50th term = 100
4)Find the total number of logs in the first 10 rows.
Sum of first n terms = n/2(a + l)
n = 10
a = first term = 2
We are told that there are 200 logs in the bottom row, hence:
l = last term = 200 logs
Hence,
Sn = 10/2×[ (2 + 200
= 5(202)
= 1010 logs
Garvin bought skis that cost $500 at the new store opening. The store gave him 60 days free credit. However, if he does not pay within 60 days they will charge him a 12 percent annual interest rate. How much interest will Garvin pay if he lets the account go for 90 days.
Answers
If Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.
If Garvin lets the account go for 90 days, he will exceed the 60-day free credit period by 30 days. This means he will be charged interest on the outstanding balance for those 30 days.
Since there is no information provided regarding any payments or partial payments made by Garvin within the 60-day period, we can assume that the full $500 is still outstanding.
Using the formula for simple interest:
Interest = Principal x Rate x Time
Principal = $500
Rate = 12% per year = 0.12
Time = 30 days / 365 days (since the rate is an annual rate)
Interest = $500 x 0.12 x (30/365) = $4.11 (rounded to two decimal places)
Therefore, if Garvin lets the account go for 90 days, he will pay approximately $4.11 in interest.

What is an equation of the line that passes through the point (5,-5) and is parallel to the line x+5y=20
Answers
Answer:
y = [tex]-\frac{1}{5}[/tex]x - 4
Step-by-step explanation:
Given parameters:
Coordinates = (5, -5)
Equation of the line, x + 5y = 20
Unknown:
Equation of the line parallel to this= ?
Solution:
To find the equation of the line, we must first understand that parallel lines are lines having the same slope. They do not cross each other at any point.
The equation of any straight line is given as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y- intercept
Now,
x + 5y = 20
Let us find the slope of this line;
5y = -x + 20
Divide through by 5;
y = [tex]-\frac{1}{5}[/tex]x + 4
The slope of the new line is the coefficient of x;
Slope = [tex]-\frac{1}{5}[/tex]
So, let us find the y-intercept of the new line;
-5 = [tex]-\frac{1}{5}[/tex] x 5 + c
-5 = -1 + c
c = -5 + 1 = -4
Now,
y = [tex]-\frac{1}{5}[/tex]x - 4
Answer: y = -(1/5)x - 4

120°=(2x + y)°
(2x - y)°=140°
Answers
Answer:
x = 65, y = - 10
Step-by-step explanation:
Given the 2 equations
2x + y = 120 → (1)
2x - y = 140 → (2)
Adding the 2 equations term by term will eliminate y, that is
4x = 260 ( divide both sides by 4 )
x = 65
Substitute x = 65 into either of the 2 equations and evaluate for y
Substituting into (1)
2(65) + y = 120
130 + y = 120 ( subtract 130 from both sides )
y = - 10

Find:
Total amount (A)
Computation:
Simple interest = (p)(r)(t)
Simple interest = (3,500)(3.25)(4)

Negatives simplifies
[tex]2y = 3x + 16[/tex]
Divided sides by 2
[tex] \frac{2y}{2} = \frac{3x + 16}{2} \\ [/tex]
