Anyone know how I can solve RL from this equation, because I have been trying and I can't get the result * this sign is to multiply
expected result is = 222.2

steps below

Step-by-step explanation:

10 = -2.5 + ((0.02*RL + 2.5) / 625)*(625+500)

0.02*RL + 2.5 = (10+2.5)*625 / (625+500)

                         = 12.5*625 / 1125

                         =6.9444444

RL = (6.9444444 - 2.5) / 0.02

     = 4.44444... / 0.02

     = 222.22222

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
