Answer: 22.6875 miles
Step-by-step explanation:
Monday = 2 3/4 miles = 2.75 miles
Tuesday = 2.75 miles
Wednesday = 2.75 miles
Thursday = 2.75 miles
Friday = 2.75 miles
Saturday = 2.5 × 2.75 = 6.875 miles
Sunday = 0.75 × 2.75 = 2.0625 miles
Total = 2.75 miles + 2.75 miles + 2.75 miles + 2.75 miles + 2.75 miles + 6.875 miles + 2.0625 miles
Total = 22.6875 miles
Answer:
The solution of the inequality in the attached figure
Step-by-step explanation:
we have

we know that
The slope of the dashed line is positive 
The equation of the dashed line is 
The y-intercept of the dashed line is the point 
The x-intercept of the dashed line is the point 
Graph the inequality
The solution of the inequality is the shaded area above the dashed line
see the attached figure
Remember that
If a ordered pair is a solution of the inequality
then
the ordered pair belong to the shaded area and the ordered pair must satisfy the inequality
