12+3/5x - 4=29

SHOW THE STEPS OR TELL HOW YOU DID IT!!!

Answers

steps are in photo..........

Answer is x= 35

12 + 3/5x - 4 = 29

Combine like terms
12+(-4) + 3/5x = 29
8 + 3/5x = 29

Get rid of you fraction by multiplying by 5 on both sides
8(5) + 3/5x (5) = 29(5)
40 + 3x = 145

Subtract 40 from each side to isolate the variable
40-40 + 3x = 145 - 40
3x = 105

Divide by 3 on both sides
3x / 3 = 105 / 3
x = 35

And done

x=35

Erin needs $100 to pay a bill. She already has $25.00 in the bank. She earns $15.00
per hour at her job. How many hours does she need to work in order to have the
$100 she needs to pay her bill?

Answers

Answer:

5 hours

Step-by-step explanation:

100 - 15 = 75

75 ÷ by 15 = 5

Erin will need to work 5 more hours to pay her bill

Answer:

5 hours

Step-by-step explanation:

Erin needs $100 to pay the bill.

She has $25 in the bank.

First let's find how much money she needs more

[tex]100-25=75[/tex]

She needs $75

They said that,

she earns $15 per hour from her job.

Let the unknown hours be x.

Now let's find the hours she have to work to earn $75

 1h = $15

 x  =  $75

Use cross multiplication

[tex]75*1=15x\\\frac{75}{15} =\frac{15x}{15} \\5 h=x[/tex]

She needs to work for 5 hours in order to have the $100

Hope this helps you.

For the function y=x+1 what is the range if the domain is 0,1,2

Answers

Step-by-step explanation:

the domain is the interval or set of the valid values of x.

the range is the interval or set of the valid values of y.

the domain here is 0, 1 and 2.

to find the range we just have to try all 3 values of x and check the results :

x = 0

y = 0 + 1 = 1

x = 1

y = 1 + 1 = 2

x = 2

y = 2 + 1 = 3

so, the range is 1, 2, 3

Answer:

  y = 3/4x +1/4

Step-by-step explanation:

Counting grid squares between the marked points, we find the point on the right is 6 units up and 8 units right of the one on the left. That means the slope of the line is ...

  m = rise/run = 6/8 = 3/4

The y-intercept can be found from the slope and one of the points. The coordinates of the point on the left are (x, y) = (-3, -2), so we have ...

  b = y -mx

  b = -2 -(3/4)(-3) = -2 +9/4 = 1/4

Then the equation of the line is ...

  y = mx +b

  y = 3/4x +1/4

Below are three advertisements for the same mini fridge from three different stores. You will need to get a credit card from one of the stores in order to buy the fridge. Complete the calculations to determine what the best deal is for you. Show your work!

Mini-Fridge Cost: $300
New Applicant Discount: 10%
Annual Interest Rate: 14.99%
Minimum Monthly Payment: $23

Mini-Fridge Cost: $285
New Applicant Discount: 5%
Annual Interest Rate: 15.99%
Minimum Monthly Payment: $19

Mini-Fridge Cost: $315
New Applicant Discount: 12%
Annual Interest Rate: 12.99%
Minimum Monthly Payment: $26


Part 1: If you only make the minimum payment each month, how long will it take you to pay off each bill AND what is your total for each credit card?

Part 2: If you pay $70 per month for the first 5 months, what will your remaining balance be for each credit card in the 6th month.

Answers

Answer:

a) 13 months, $293.82. b) 16 months, $302.25. c) 12 months, $296.18a) $71.55 cr. b) $70.17 cr. c) $65.13 cr. (Or, all are 0 in the 6th month)

Step-by-step explanation:

Part 1

The attached spreadsheet shows the remaining balance after each payment for each of the payment scenarios. The negative balance at the end of the payment period represents the credit that the account would have if the last payment is the full minimum payment amount. In real life, the last payment would be reduced by that value.

Card A. The 13th payment will result in a credit. It takes 13 months to pay off the credit card. The total of payments is 13×$23 -5.18 = $293.82.

Card B. The 16th payment will result in a credit. It takes 16 months to pay off the credit card. The total of payments is 16×$19 -1.75 = $302.25.

Card C. The 12th payment will result in a credit. It takes 12 months to pay off the credit card. The total of payments is 12×$26 -15.82 = $296.18.

The best deal is Card A.

__

Part 2

All of the cards will be completely paid off in 5 months. The remaining balance in the 6th month is zero. The above "Answer" block shows the credit balance each card will have if payments continue to be made for 5 months.

The best deal is Card A, which will have the lowest total of payments.

_____

How the calculations are done

The balance at each step in the spreadsheet is computed as ...

  (previous balance) × (1 + rate/12) - (payment)

For example, the balance after the first payment on card A is ...

  $270 × (1 +0.1499/12) -23.00 = $273.37 -23.00 = $250.37

Each calculation is rounded to cents, as it would be on a real credit card.

Matt is planning his spring flower garden. He wants to plant tulip and daffodil bulbs. He will plant 8 times as many daffodil bulbs as tulip bulbs. If he wants to plant 270 bulbs, how many tulip bulbs and how many daffodil bulbs should he plant?

Answers

divide 270 and 9- and you will get thirty. there are going to be 30 tulip bulbs and 240 daffodil bulbs.
(D)affodil = 240
(T)ulip = 30

D = 8 x T
D + T = 270

8T + T = 270
9T = 270
270 divided by 9 = 30
T = 30
30 x 8 = 240
D = 240

(Add to check, 30 + 240 = 270
