PLEASE HELP ME WITH MATH
Alexxandr [17]

Answer:

down below

Step-by-step explanation:

1) 4% of 120 = 4.8, so 120+4.8 = 124.8 cm tall

2) 12% of 6000 = 720 .  6000-720 = 5280 gallons

3) 22% of 200 = 44 . 200-44 = 156

4) 30% of 40 - 12 .   40 - 12 = $28

5) 35% of 140 = $49 .  140 + 49 = $189

Am trying to find the value of r<br> 1/r + 2/1-r = 4/r^2
Mashcka [7]
<span>1/r + 2/1-r = 4/r^2

1-r+2r/r(1-r)=4/r^2
(1+r)/r(1-r)=4/r^2   cancle r both side

1+r/1-r=4/r

cross multiply 
r+r^2=4-4r
r^2+4r+r-4=0
r^2+5r-4=0
r^2+4r+r-4=0
solve it for r factor it...
