Explanation:
Let’s take kids as x and adults as y
According to the question,
5x + 2y = 25 (1)
3x + 1y = 14 (2)
Let’s multiply (2) with 2 so take we can solve the equations
5x + 2y = 25
6x + 2y = 28
(-) (-) (-)
___________
-1x = = -3
x = 3
Substituting to get y
3x + 1y = 14
3(3) + y = 14
y = 14-9
y = 5
Answer:
Therefore, each child’s skate rental (x) costs $3 and each adults’s skate rental (y) costs $5
Hope it helped! :)
For number 1: Place a dot on about 1.7 Because 1 2/3 is equivalent to 1.6 repeated (which rounds up to 1.7.)
For number 3: Place a dot at -2.4 and -1.6 because -2 3/5 is equivalent to -1.6.)
Hope this helps! Good luck and have a nice day!

Required
Determine the domain and the range
From the complete question, we understand that the study was carried out for 6 days. This represents the domain;
So, we have:
i.e. from day 0 to day 6
Also, he experimented with 72ml, and he used an equal amount each day before he used up all the 72mL. This represents the range
So, the range is:
i.e. from 72mL to 0mL
