Eduardo rented a bike from James' Bikes. It cost $19 plus $6 per hour. If Eduardo paid $49 then he rented the bike for how many

solniwko [45]

So to solve this, you would have to write the equation, which is 49=6x+19

Then solve your equation.

49=6x+19
-19 -19
30=6x
/6 /6

5=x

So he rented it for 5 hours.

Let's calculate for the tablespoons of sugar to tablespoons of milk ratio for Mark, Sharri and Eve.

Mark: 3/2 = 1.5
Sharri: 4/3 = 1.3
Eve: 9/6 = 1.5
