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

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

y=1/2x-1/2
Step-by-step explanation:
To find the slope you do 2-1/5-3 = 1/2 x
then substitute with a coordinate like
y=mx+b
1= 1/2(3) +b
1=3/2 +b
b = -1/2
then combine them
y= 1/2x -1/2

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.

Answer:

Step-by-step explanation:
(x + 53)° + (x + 74)° + 73° = 180°
(x + 53 + x + 74)° = 180° - 73°
(2x + 127)° = 107°
2x + 127 = 107
2x = 107 - 127
2x = - 20
x = - 20/2
x = - 10
