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.

<em>The correct answer is 1 1/2</em>
<u>Step-by-step explanation:</u>
<em>First, We need to find out the sum of 2/3 x 3, change 3 into a fraction if you want</em>
<em>3x2=6 and 1x3 is 3, So 2/3 x 3 is 6/3 or 2</em>
<em>Next, divide 3 by 2, change to fractions if needed</em>
<em>Remember keep, change and flip, flip 2/3 to 1/2</em>
<em>Then, you multiply 3/1 and 1/2 3x1=3 1x2=2</em>
<em>Finally divide 3 by 2. 3 ÷ 2 is 1 1/2</em>
<em>I hope this helped!</em>
