Ashley has two jobs: mowing lawns and babysitting. She earns $9 per hour mowing lawns (x) and $7 per hour babysitting (y). She also wants to earn at least $147 per week. Write an inequality in standard form to describe all possible combinations to the limitation above

The correct answer is 9x + 7 y 147 where Ashley works for x hours as lawn mower and y hours as babysitter per week.

Step-by-step explanation:

Ashley works in two different jobs namely mowing lawns and babysitting.

Let Ashley mow lawn for x hours and babysit for y hours in a week.

Ashley's earning for every hour she mow is $ 9. Total earning mowing lawn is $ 9x.

Ashley earns $7 for every hour she babysit. Total earning babysitting is $ 7y.

Total earning per week $ (9x + 7y).

Ashley's earning per week is at least $147.

∴ The required inequality to describe the above case is 9x + 7 y 147.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
