Answer:
y = 3x equation represent direct proportion.
Step-by-step explanation:
Direct Proportion:
If x value increases then y value also increases. This is called direct variation or y is directly proportional to x.
For y = 3x
x = 1 , then y = 3
x = 2 , then y = 6
So on, here x is increasing then y is also increases.
Hence, y = 3x equation represent direct proportion.
Inverse Proportion:
If x value increases then y value decreases. This is called indirect variation or y is inversely proportional to x.
For y = -2x + 1
x = 1 , then y = -1
x = 2 , then y = -3
So on, here x is increasing then y decreases.
Hence y = -2x + 1 is Indirect variation.

Answer:
one forty fifth times five equals one ninth
Step-by-step explanation:
In division, the number being divided is the dividend or numerator, the denominator is the number we use to do the division while the result is the quotient and there may be a reminder.
For example, if
a/b = c
then
a = b * c
hence
1/9 ÷ 5
= 1/9 * 1/5
= 1/45
This means that
1/45 * 5 = 1/9
Hence the related multiplication equation related to the division equation one ninth ÷ 5 is one forty fifth times five equals one ninth
It takes 3 pumps 16 hours to empty a tank
Meaning it takes 48 hours for one pump by its self
So if there are 4 pumps
48/4 it would take them 12 hours
They would need to work 12 hours to do it in 1 day
