You have a summer job mowing lawns. You mow 3 lawns in 5 hours. How long will it take to mow 9 lawns. Explain your thinking.

15 hours

Step-by-step explanation:

2 ways to do this

1- I know that 3 x 3 is 9 hours which will leads to these equations

3 x 3 = 9

5 x 3 = 15

2- Find out how long it takes for one lawn

5/3 = 1.6666...

1.6666 x 9 =15

I hope Im correct!

it would take 15 hours

Step-by-step explanation:

If we know that it would take 5 hours to mow 3 lawns, then we can assume that this ratio will stay the same and multiply this by 3, making it 9 lawns in 15 hours

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
