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:
-5x - 6y + 8
Step-by-step explanation:
-2(x - 4) -3(x + 2y)
-2x + 8 - 3x - 6y
-5x - 6y + 8
Hope this helps!
Answer:
<h2><u>26°</u></h2>
Step-by-step explanation:
Assuming that your figure is a triangle, we should keep in mind that all the interior angles of a triangle add up to 180°, always.
So, we have the values of angles x and y as 90° and 64°.
90 + 64 = 154° ⇒ Add them up.
Now, subtract 154 from 180 to get ∠z.
180 - 154 = <u>26°</u>
Answer:
1/6 and 3/18
Step-by-step explanation:
I used the butterfly method to compare all the fraction pairs together and then 1/6 and 3/18 were equal. Hopefully I can help you.
