Say he needs to mow 'x' no of lawns to go on trip,

<u>So money he will get by mowing lawn</u>

=$20x

which is the amount of money he needs

(=$125)

But he already has $45.

So,

$125-$45=$80 is the amount of money he will require just to go trip.

i.e. ,

➧20x ⩽80

which is the required inequality.

<u>Divide both sides by 20,</u>

<h3>➧x⩽4</h3>

<u>which means he needs to mow </u><u>4</u><u> lawns to go on trip.</u>

Answer:

9) 844cm^2 10) 15,000in^3 11) 240cm^3 12) 480in^3

Step-by-step explanation:

9) A= 200 A=160 A=192 A=192 A=100

200+160= 360+192= 552+192= 744+100=844cm^2

for #9 i divided the figure into 5 parts and got the area of each one and added all of the totally areas to get the final answer

10) A= 20*30= 600*25= 15,000in^3

11) A= 2*5= 10*4= 40cm^2 (cheese) A= 40*6= 240cm^3

12) 12*10= 120*4= 480in^3
