y=0.625x+1.75 is the equation for your problem.
Hey!
Let's write the problem,

Multiply both sides by

in order to undo the fraction.


Let's switch sides so that we end up with

on the left side.

Divide both sides by

.

Our final answer would be,

If the hundreth digit is equal to or larger than 5, increase the tenths digit by 1 and get rid of the hundreths digit altogether.
X = gym memberships, and y = bottles of water
30x + 7y = 1050.....when x = 28
30(28) + 7y = 1050
840 + 7y = 1050
7y = 1050 - 840
7y = 210
y = 210/7
y = 30....so he would have to sell 30 water bottles
Average speed for Jaden’s train
= 130 km / (75/60) hours
= 130 km / 1.25 hours
= 104 km/h
Dani’s train travels from 15:15 to 18:30, which is 3 hours and 15 mins.
3 hours and 15 mins = 3.25 hours
Average speed of Dani’s train
= 312 km / 3.25 hours
= 96 km/h
Difference
= 104 - 96
= 8 km/h
