Answer:
The pair of linear equations is
x+y = 75
y+15 = x
Step-by-step explanation:
x = number of minutes Jack jogs
y = number of minutes Jack bikes
Total of 75 minutes for jogging and biking
x+y = 75
He bikes for 15 minutes longer than he jogs
y+15 = x
The pair of linear equations is
x+y = 75
y+15 = x

Answer:
Question 6

Question 7
The width is 2x.
Step-by-step explanation:
Question 6)
Expand

solving to the expand


so the expression becomes



adding similar elements: 20a+2a=22a

Hence,

Question 7)
Given
Using the formula
width = Area/Length

∵ 
Therefore, the width is 2x.
