For explicit equations with the first term, you use the form [tex]f(n)=f_{1}+d(n-1)[/tex]. (f of 1 is the first term, d is the common difference, n is the step number)

However, since it is an admission fee before you go on rides, you do not need the -1 because it is not from the first term. Then, you can plug the values you know in.

f(n)=5+2n

Mia has
6 1/8
yards of cloth. If she uses
3 1/4
yards to make a skirt, how many yards will she have left?

Answers

Answer:

2 7/8

Step-by-step explanation:

first step is making these into improper fractions for example 6 1/8 would equal 49/8 because 6*8=48 and add the 1/8 to get 49/8 then do the same with the 3 1/4 make them into 8ths. so it would be 3 2/8 then 26/8 now subtract 49-26 to get 23/8. now simplify to get 2 7/8

Answer:

2 7/8

Step-by-step explanation:

In order to find the difference, you need to convert both fractions.

The common denominator here is 8, so 3 1/4 becomes 3 2/8.

You cannot subtract 2/8 from 1/8 so the 1/8 becomes an improper fraction.

Now you have 5 9/8 - 3 2/8

5 - 3 = 2 and 9/8 - 2/8 = 7/8 so your answer is 2 and 7/8

Mia has 2 7/8 yards left after she makes a skirt.

A store owner offered a 40% discount off the regular price of a piece of furniture. The amount of the discount was $72. What is the original price of the mirror?

Answers

Answer:

120

Step-by-step explanation:

120- 40%= 72

Try that

Answer: $180




Step by Step Explanation:

72 is the price with 40% off, so it will not be the total price.

100%, is the total price without the discount (40%).

To get the total price, we multiply 72×100 (The discounted price, and the total percentage price).

Then you have, 7200, and you divide that by 40 (The discount).

This gets you to $180. That is the total price.


Checking:

To check if this is correct, we multiply 180, and the discount 40.

This will be 7200.

Then we divide that by 100.

This will leave us with 72, the original discounted price.

My winter plan is going to out and doing enjoy lots.and I will go with my friends and do enjoy .

For winter break I plan to spend time with my family. I don’t have any plans that I know of right now besides helping family out. I do plan on hanging out with my friends some time this winter break. I might go to the park with a few of my friends and hangout with them. I mostly plan on spending time with family and having fun.

Sometimes I prefer to be alone when being with people is to much. I sometimes just want to be in my room away from everyone but not all the time. It’s better for me to be around people and family and have human interaction. When I’m alone I’m usually bored so I always try to find something to do. Most of the time I would rather hang out with friends and have fun.

Step-by-step explanation:
If j=3, k=6, m=12 the equation would be re-written as
3*6 + (4*12)/2
=18 + (48/2)
=18 + 24
=42

Hey there!

jk + 4m/2


= 3(6) + 4(12)/2

= 18 + 48/2


= 18 + 24


= 42


Therefore, your answer is: 42

Tim worked on a math problem 4+3(2+5) Tim should have gotten 25 for an answer, but he got 49 for an answer. What is Tim's percent error? (Be sure to put the percent sign in your answer. )

Answers

Answer:

96% error

Step-by-step explanation:

Step 1. Subtract the actual value (25) from the estimated value (49)

49-25 = 24

Step 2. Divide the results (-24) with the actual value (25)

24/25 = 0.96

Step 3. Find the percent by multiplying the result (0.96) by 100

0.96 * 100 = 96

Therefore, the percent error was 96%
