A student pays for pounds of apples with a ​$ bill. How much change does the student​ receive? Answer parts a and b. a. What do you do first to solve the​ problem? ▼ the number of pounds of apples by the price per pound

Answers

A student pays for 8.9 pounds of apples with a 10$ bill. Its $1.09 per pound. How much change does the student receive? What do you do first to solve the​ problem?

Answer:

$0.299

Step-by-step explanation:

Given that :

Pounds of apple purchased = 8.9 pounds

Price per pounds of apple = $1.09

Bill issued = $10

First, we calculate the total cost of 8.9 pounds of apple :

(Number of pounds * price per pound)

($8.9 * 1.09) = $9.701

Amount of Change :

Bill issued - total cost

$10 - $9.701

= $0.299

Answer:

$3,000 was invested in the account that gained 13%

$17,500 was invested in the account that lost 10%

Step-by-step explanation:

Let the amount in both accounts be x and y

x for the first and y for the second

Adding both is 20,500

x + y = 20,500 •••••(i)

First account earned 13% profit

= 13/100 * x = 0.13x

Second account, a loss of 10%

= -10/100 * y = -0.1y

Total loss of -1,360

This is;

-0.1y + 0.13x = -1,360 •••••••(ii)

From i, x = 20,500-y

Insert this into ii

-0.1y + 0.13(20,500-y) = -1,360

-0.1y + 2665 -0.13y = -1360

-0.23y = -1360-2665

-0.23y = -4025

y = -4025/-0.23

y = 17,500

To get x, we have

x = 20,500 -y

x = 20,500- 17,500

x = 3,000

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21

Answers

Answer:

d.21

Step-by-step explanation:

840/40=21

Answer:

21 Weeks

Step-by-step explanation:

$840 ÷ 4 weeks = 21

You can also reverse work this by multiplying $40 by the other choices!

$40 x 40 = $1600

$40 x 35 = $1400

$40 x 32 = $1280

$40 x 21 = $840

As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

Answers

Answer:

(-10, 9)

Step-by-step explanation:

9x+9y=-9

Use substitution method

9(-10)+9y=-9

Order of operations(PEMDAS)

-90+9y=-9

Add 90 to both sides

(-90+90)+9y= -9+90

9y=81

Divide 9 from both sides

(9/9)y=81/9

y=9

Hope this helps. Have a nice day. May it be filled with joy and happiness. Please, stay safe and wash your hands. Happy Holidays.

Answer:

Step-by-step explanation:

in this case, we already know that x=   -10 so we can substitute in the other problem, -10x9 = -90 so now we can get rid of that by adding + 90 on each side making it 9y=81 by this time, we see that both sides are divisable by 9 divide both by nine and you get: 1y=9 from that you can finally answer the question with

x= -10 y= 9

(2x + 127)° = 107°

2x + 127 = 107

2x = 107 - 127
