Answer: x= -2, y= 3
Step-by-step explanation:
3x+5y=9
X-y=-5
Multiply bottom equation by 5
3x+5y=9
5x-5y=-25
3x + 5x=8x
5y-5y cancels out
9-25= -16
8x= -16
X= -2
Plug -2 back into equation of choice to find y
3(-2)+5y=9
-6+5y=9
Add -6 to both sides
-6+6 cancels
9+6=15
5y=15
Y=3
15x^6/20y^5 * 6y^2/5x^4 when simplified becomes 9x^2/10y^3
Answer:
180 points.
Step-by-step explanation:
Given:
A class will have 1 test and 5 homework assignments to complete.
The test is worth 80 points.
Each homework assignment is work 25% of the test.
Question asked:
How many points may be earned during this unit ?
Solution:
By unitary method:
Points may be earned from 1 assignments = (given)
=
Points may be earned from 5 assignments =
Points may be earned from 1 test =
Total points may be earned = 100 + 80 = 180
Therefore, 180 points may be earned during this unit.
In order to have the least amount of each, you would need to purchase 2 packages of large plates. Here is the reasoning:
You can buy the following number of large plates and small plates:
Small: 8, 16, 24, 32, ...
Large: 12, 24, 36, ...
The smallest number that can be bought so you have an equal amount is 24 of each.
To get 24 large plates, you would need 2 packages.
