Hi
18.5 ⇒ 100% of the number
x ⇒ 46% of the number
100x = 46·(18.5)
100x = 851
x = 851/100
x = 8.51
Answer: 8.51
Solutions
1hr = 60 min
180 ÷ 60 = 3
180 min = 3 hrs
First you need 0 on the right side of the equation so you subtract x
you get x^2 - x - 6 = 0
you can factor this into (x-3)(x+2) = 0
x = 3,-2
Ans B
Answer:
3x+1=10, x =3
-3+8n=-5 x =-1
4h-6=22 h =7
hope this helped you out!
