Answer:
c < 7
Step-by-step explanation:
3(6-5c)-2c>4c-129
You will first multiply 3 with 6-5c which will give you 18 and -15c.
18-15c-2c>4c-129
Then you will subtract 2c from -15c because they're like terms. That will give you -17c.
18-17c>4c-129
Next you will put all the variables to one side. To do this, you will add 17c to 4c. You add 17c because that way, you cancel out the -17c and all the variables will be on one side
18>21c-129
Then you will add 129 to both 18 and -129 so that all of the numbers without variables can go on on side.
147>13c
Finally you divide both 147 and 13c by 13. That should give you the final solution of 7>c, or c<7.

find the 40th term of an AP where 12th term is 45 and 17th term is 80.
Answer:
40th term = 241.
Step-by-step explanation:
17th term:
= a1 + 16d = 80
12th term
= a1 + 11d = 45 Subtracting the 2 equations:
5d = 80 - 45 = 35
d = 7
and a1 + 16(7) = 80
a1 = 80 -112 = -32.
Therefore the 40th term = -32 + 39*7
= 241.

Step-by-step explanation:
after paying income 5% a man has Rs 7600 left. what is his income?
Answer:
His income was 8000 rupees
Step-by-step explanation:
We must find his income so let that be x
We take 100%-5% = 95%
Turn this 95% into a decimal which is 0.95
So:
x * 0.95 = 7600
Rearrange this to give x:
x = 7600/0.95
x = 8000 rupees
The man's income is Rs. 8000. He has been left with 95 percent of his income = Rs. 7600.
What are percentages?Percentages are fractional values where the total amount is taken as 100.
25% of a quantity means 25/100 of that quantity.
How to solve the given question?In the question, we are informed that after paying 5% of income, a man is left with Rs. 7600.
We are asked to find his income.
We are given that a man pays 5% of his income, so he will be left with (100-5)% = 95% of his income as percentages are taken over a total of 100.
We assume the man's total income to be Rs. Y.
∴ We can say that the man is left with 95% of Y.
We know the man is left with Rs. 7600. So we can write this case as:
95% of Y = 7600
or, 95/100 of Y = 7600
or, (95/100)*Y = 7600
or, Y = (7600*100)/95 = 760000/95 = 40000/5 = 8000.
∴ The man's income is Rs. 8000. He has been left with 95 percent of his income = Rs. 7600.

On Friday there were 8 snowboarders for every 3 skiers at Slovak ski resort. On Saturday the ratio of the number of snowboarders to the number of skiers was 4:7 there were 168 snowboarders at the ski resort on Friday there were the same number of people at the ski resort on Saturday as there were on Friday how many more skiers were there than snowboarders at the ski resort on Saturday
Answer:
There are 46 more skiers than snowboarder
Step-by-step explanation:
Given
Ratio of Snowboarders to Skiers
On Friday:
[tex]Ratio = 8 : 3[/tex]
On Saturday:
[tex]Ratio = 4 : 7[/tex]
Population = 168
Required
Determine the difference in the number of skiers and snowboarders on Saturday
On Saturday, we have
[tex]Ratio = 4 : 7[/tex]
Calculate Total
[tex]Total = 4 + 7[/tex]
[tex]Total = 11[/tex]
Calculate the number of skiers
[tex]Skiers = \frac{7}{11} * 168[/tex]
[tex]Skiers = \frac{1176}{11}[/tex]
[tex]Skiers = 107[/tex] (Approximated)
Calculate the number of snowboarders
[tex]Snowboarders = \frac{4}{11} * 168[/tex]
[tex]Snowboarders = \frac{672}{11}[/tex]
[tex]Snowboarders = 61[/tex] (Approximated)
Calculate the difference
[tex]Difference = 107 - 61[/tex]
[tex]Difference = 46[/tex]
Hence, there are 46 more skiers than snowboarder

Find m∠XYZ in the figure if ∠XYZ and ∠PQR are supplementary angles. please explain your answer Question 1 options: A) 83° B) 7° C) 173° D) 97°
Answer:
It's D) 97°
Step-by-step explanation:
Just stick this in ya brain
Supplementary angles => sum => 180
Answer:
D
Step-by-step explanation:
So, we know that ∠XYZ and ∠PQR are supplementary angles. This means that their total sum is 180 degrees. In an equation, this is:
[tex]\angle PQR+\angle XYZ=180[/tex]
Since we already know the measure of PQR, substitute 83 for PQR:
[tex]83+\angle XYZ=180[/tex]
Subtract 83 from both sides:
[tex](83+\angle XYZ)-83=(180)-83\\\angle XYZ=97\textdegree[/tex]

What is the solution set for 5x – 1 < 7x - 47
Answer:
x > 23
Step-by-step explanation:
5x – 1 < 7x - 47
Add 1 to -47, you get -46.
5x < 7x - 46
Subtract 7x from 5x.
-2x < -46
Multiply both sides to reverse the inequality.
2x > 46
Divide both sides by 2.
x > 23

Solve the equation below for x.
сх — 4 = 7
Answer:
x = 11/c
Step-by-step explanation:
To solve this equation for x, we simply need to apply equation operations and isolate the x variable.
cx - 4 = 7
cx - 4 + 4 = 7 + 4
cx = 7 + 4
cx = 11
cx * (1/c) = 11 * (1/c)
x = 11 * (1/c)
x = 11/c

An item is on sale for $100. If it was discounted by 20%, what was the original selling price?
Answer: The original price was $125
Step-by-step explanation:
If an item is on sale for $100 and it was discounted by 20% then we could set up an equation and solve for the original price.
Remember if there were 20% discount then 80% of the price will be left.
80% * x = 100
0.8x =100
x = 125
Step-by-step explanation:
We have :
• Selling Price = $100
• discount = 20%
As we know
• Selling Price = Cost - Discount
Now we have
• Discount = 20%
Let cost be x
→ Selling Price = x - 20% of x
→ selling price = 80% of x
→ 80% of x = 100
→ 80/100 x = 100
→ x = 100 × 100 / 80
→ x = $ 125
