Which equation is correctly rewritten to solve for y?
12y + d = –19y + t
A. Y= t+d/-7
B. Y= -7(t+d)
C. Y= t-d/31
D. Y= 31(t-d)

Answers

Answer 1

Answer:

C. y=(t-d)/31

Step-by-step explanation:

Step 1: Add 19y to both sides.

31y+d=t

Step 2: Add -d to both sides.

31y=t-d

Step 3: Divide both sides by 31.

y=(t-d)/31

Answer 2
I think it would be C

Part 1.

A is.

45 and 34 wood pieces left

B is.

It takes 11 cause 100-89=11 and 11+89=100 and it keeps subtracting 11.

C is.

I dont understand the question(sorry)

D is.

At least 9 shelves,

100-11=89

89-11=78

78-11=67

67-11=56

56-11=45

45-11=34

34-11=23

23-11=12

12-11=1

And you would have 1 wood piece remaining!!

Question 1.
Part one
A. After you build 5 you get 45 pieces, then after you build 6 you get 34.

B. It takes 11 pieces of wood to build each shelf

C. It is negative since y is decreasing in value, while x increases

D. you can build nine shelves
Not sure if there is a specific method you need to use, but you can just do 100 divided by 11 to get 9 remainder something, but you can only build full shelves.

Part 2
A. It took 20 minutes to set up building materials, since the line starts at the y-intercept at (0,20)

B. It takes 25 minutes to build each shelf, since the graph shows that after the first shelf there was a twenty five minute increase from 20 to 45

C. If you work at a constant rate it will take 225 minutes to build nine shelves, you can do this by either multiplying 9 by 25 or continuing the line on the graph.

D. You spent 320 minutes preparing and building 12 shelves. Since we already know it takes 20 minutes to prepare, you just need to multiply 12 by 25 to get 300, then you add them together to get 320.

E. This line represents the amount of time it takes to build shelves


Question 2

A.the initial deposit was $95

B. The line would represent the decrease of money in your account, caused by the maintenance fee.

C. The line will be negative since the y outputs decrease by 6.5

D. The monthly maintenance fee is $6.5, you know this by looking at the difference in outputs

E. After sixth months in total, the remaining balance is $56, you multiply 6.5 by 6 months to get 39, then subtract that from 95.

F. Your balance will be negative after 15 months, just divide 95 by 6.5 then round the answer up

Quiana took out a loan to pay for a new car. Initially, she owed the lender $15,234.68. She has repaid $247.43 of the loan each month for the past 5 months. What is the net change to the loan from Quiana’s perspective over the past 5 months?
Quiana made five equal monthly payments from her bank account. Which rational number shows something being removed five times?

Answers

Answer:

247.43 times 5 =1237.15

15,236.86-1237.15=13999.71

13999.71 divide 5=2799.942

Step-by-step explanation:

The rational number is 5 months

Answer:

Answer: $1237.15

Step-by-step explanation:

Initial loan amount = $15,234.68

Monthly payment =$247.43

Payment's made in last five(5) months = $247.43 × 5

= $1237.15

Current balance

= $15,234.68 - $1237.15

= $13,997.53

Net change

= Initial loan amount - current balance

= $15,234.68 - $13,997.53

= $1237.15

Answers

Answer:

8.80

Step-by-step explanation:

The decimal is 8.8

What is Decimal?

A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.

given:

8 4/5

Now, writing into normal fraction

8 4/5 = 44/5

Now, dividing the fraction

44/5 = 8.8

Hence, the decimal is 8.8

PLZZ HURRY!! What numbers are a distance of 1/2 unit from 3/5 on a number line? Select the locations on the number line to plot the points.

Answers

Answer:

Step-by-step explanation:

The numbers that are a distance of 1/2 unit from 3/5 on a number line are the numbers that are 1/2 units to the right and to the left of 3/5 on the number line.

The numbers are given by 3/5 - 1/2 and 3/5 + 1/2.

The numbers are 1/10 and 1 1/10

The required numbers are 0.1 and 1.1 are a distance of 1/2 unit from 3/5 on a number line.

What is Number Line?

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

We have been given that number line, the numbers that are 1/2 units away from the number 3/5 are the numbers that are 1/2 units to its right and left.

The numbers are given by 3/5 - 1/2 and 3/5 + 1/2.

So the required numbers would be:

⇒ 3/5 - 1/2 = 1/10 = 0.1

⇒ 3/5 + 1/2 = 11/10 = 1.1

Therefore, the required numbers are 0.1 and 1.1 are a distance of 1/2 unit from 3/5 on a number line.

Nina saved money in her piggy bank to buy a music player she started by saving 30$ that she received for her birthday and then she saved 10$ from her allowance each month for 6 months. The table below shows the total amount of money Nina had save at the end of each month for 6 months .

Answers

Answer:

No, it does not represent a proportional relationship.

Step-by-step explanation:

The ratios do not reduce to the same value.

40/1 = 40

50/2 = 25

60/3 = 20

We can also tell straight away that this is not a proportional relationship because Nina starts with $30. If the data were graphed, this would mean that the line would not go through the origin. It would start at 30 on the y axis.

Yes because if she had $40 together and added 10 every 6 month it will get her to $90

Lazarus’ Boat Rentals charges a yearly fee of $105 and $9.50 each time a member wants to rent a boat. Robert’s Boat Rentals does not charge a yearly fee but charges $14.75 every time a member rents a boat. How many times would a person have to rent a boat for Lazarus’ and Robert’s charges to be equal

Answers

Answer:

The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times

Step-by-step explanation:

Answer: The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal is 20 times

Step-by-step explanation:

The given information are:

For the Lazarus' Boat Rentals company

The yearly charges by Lazarus' boat company = $105

The charge each time a member rents  a boat  = $9.50

For the Robert's Boat Rentals company

The yearly charges by Robert's boat company = $0

The charge each time a member rents  a boat  = $14.75

Let the number of times required before the charges for both Lazarus' Boat Rentals company and Robert's Boat Rentals company to be equal, we have:

$105 + $9.50 × t = $14.75 × t

∴ t = $105/($14.75 - $9.50) = 20 times

The number of times a person would need to rent a boat for Lazarus' and Robert's charges to be equal = 20 times.

He buys almost everything he needs or wants, including clothes, food, and entertainment with his card. When Lindsey asked him about the balance calculation method, APR, grace period, or other fees and features of his card, Garth was clueless. He reasoned that his credit card was a safe and convenient way to shop and it allowed him to buy expensive items by paying minimum monthly payments. Overall, Garth thought of himself as a responsible credit user, despite the fact he had been late making a few monthly payments, and, once or twice, had gone over his credit limit.
