Answer:
7/10 or 0.7
Step-by-step explanation:
cross multiply to get 40x+20=48
subtract 20 from both sides to get 40x=28
divide both sides by 40 to get 7/10
HOPE THIS HELPS!!!:)
What you have to do is rearrange the equation by subtracting what is on the right of the equal sign from both sides of the equation
so it would be 4*x-13*x-(27)=0
<span>first you set up a proportion 18 over ? = 60 over 100 then cross multiply. 18*100=1800 then divide that by 60 and you get 30 :)</span>
X= 49 because the square root of 49 IS 7. :D
Good luck! :)
