The expression 3.5d + 5 represents the number of miles Erin ran last week when she ran 5 miles on Sunday and 3.5 miles each day after Sunday. The expression 2.5d + 3 represents the number of miles Luis ran last week when he ran 3 miles on Sunday and 2.5 miles each day after Sunday.

I am assuming the question how many miles did they run last week so.

Step-by-step explanation:

d=6(because sunday was 5 miles we don't count that)

3.5*6=21

21+5=26

Erin ran 26 miles last week.

d=6(because sunday was 3 miles we don't count that)

2.5*3=7.5

7.5+3=10.5

Luis ran 10.5 miles

In case the question was how many more miles did Erin run than Luis it would be, Erin ran 15.5 more miles than Luis.

Hope this helps.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
