Leena knits 10 rows in 12 min. at this pace, how long will it take her to knit the next 25 rows?

62.5 minutes

Step-by-step explanation:

10 rows

= 2/5 row/min

25 min

This is equivalent to 5/2 minutes per row.

Mult. this by 25 min to determine how many rows Leena can knit in that period:

5 min       25 rows

* = 125/2 minutes, or 62.5 minutes

2 row          1

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

x+10

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
