Hey there! I'm happy to help!
Let's have the capacity be c. The tank is currently at 4/5c. We subtract 190 and then we are at 1/6c. Let's set this up as an equation and solve it.
4/5c-190=1/6c
We want to get the c all by itself to see the capacity of the tank. Let's get all of the c values on the left side of the equation and the numbers on the right by using inverse operations.
4/5c-190=1/6c
Add 190 to both sides.
4/5c=1/6+190
Subtract 1/6 from both sides.
19/30c=190
Divide both sides by 19/30.
c=300
So, the capacity of the tank is 300 liters of water.
Have a wonderful day and keep on learning! :D
Probably you are supposed to compute

Factorize the numerator and denominator, then simplify:
The answer is not right i just need the time or what ever2
Answer:
D
x >= -8
multiply by 2
-X <= 8
divide by -1
X >=-8 (remember flip sign if multiply by negative)

Answer:
a 3
Step-by-step explanation:
You make 50 a day plus 3.60 per sale
Income = 50+ 3.6 s
You want to make at least 60
60 ≤ 50+ 3.6 s
Subtract 50 from each side
60 -50 ≤ 50-50 +3.6s
10 ≤ 3.6s
Divide by 3.6 on each side
10/3.6 ≤ 3.6s/3.6
2.7777777 ≤ s
You must make more than 2.7777 sales
But you cannot make part of a sale so
You must make at least 3 sales
