the question is asking how much water the pond is losing over 5 weeks the pond loses 2 inches each week so if were going over the time span of 5 weeks the equation would 2×5=10
Answer:
(3,2)
Step-by-step explanation:
3x + 4y=17
- 4x – 3y= - 18
Multiply the first equation by 4
4(3x + 4y=17
)
12x +16y = 68
Multiply the second equation by 3
3( - 4x – 3y= - 18)
-12x -9y = -54
Add the new equations together to eliminate x
12x +16y = 68
-12x -9y = -54
-----------------------
7y = 14
Divide by 7
7y/7 = 14/7
y=2
Now find x
3x+4(2) = 17
3x+8 = 17
Subtract 8 from each side
3x+8-8 = 17-8
3x = 9
Divide by 3
x = 3

sorry man i wish i could help
Answer:
Step-by-step explanation:
we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.
Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.
The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:
Hence the required inequality has been formulated.
Answer: $0.35 which is the same as 35 cents
==========================================
Work Shown:
3 cookies = $1.05
3/3 cookies = $1.05/3
1 cookie = $0.35 = 35 cents
