Which variable of time could cause a student’s gpa to increase?

a) sleeping

b) working

c) eating

d) studying

The correct answer would be D) Studying.

Step-by-step explanation:

Sleeping equates to wasting your time when you could be getting better grades. Working, depending on the meaning could help, but I'm going to assume this means having a job. This does not help raise your GPA. Eating is the same as sleeping, while it is a necessity of life, it does not benefit your GPA. Studying is the only one that makes sense because through studying, you can achieve higher grades and grades directly affect your GPA.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
