Answer:
Multiply input by 4.
Step-by-step explanation:
So, all we have to do is find the difference between the input/output.
So for the first one.
4y=1x
Divde both sides:
1y=1/4x
Next we have 16y=4x
Divide both sides:
1y=1/4x
Ok, so we now know that y is 1/4x
Or in otherwords, 4x is 1y.
Remember x is input, and y is output.
So we can think of this as the input times 4 equals the output.
This seems to be the second answer.

sorry didn't understand 8
4*5,2*12,in any even number way
3. 45/3= 15, so she runs 1 mile in 15 minutes.
4. 45/9= 5, so each square foot can contain 5 plants.
Hope this helped!!
Divide the number of people selected by the total number of people.
90/500 = .18
This means that 18% of the customers were selected for the survey.
If the probability is the same on Saturday, then we can multiply the expected customers by our .18
700 x .18 = 126
126 should be selected for the survey on Saturday.
