The answer is 1.84 If you were to write the equation 4.5-4.66-5+7
To solve this problem, we can set up an equation using the variable x to represent the unknown number of hours Julio rented the bike for. We know that Julio paid 23 dollars total, so this must be one side of the equation. This should be set equal to the standard 12 dollars plus the added 2.20 multiplied by the number of hours Julio rented the bike for (represented by x). This is as follows:
23 = 12 + 2.20x
Now, we must solve this equation. To begin this process we must subtract 12 from both sides of the equation.
11 = 2.20x
Finally, we must divide both sides of the equation by 2.20 because we must cancel out the coefficient on the variable x in order to isolate it.
5 = x
Therefore, Julio rented the bike for 5 hours total.
Hope this helps!
Answer: The plane is flying at 990 miles per hour and the wind is blowing at 190 miles per hour.
Step-by-step explanation: 1. Start by setting up the equations.
3200 = 4(x-y)
9440 = 8(x+y)
2. Simplify them by dividing the first one by 4 and the second one by 8. This gives you:
800 = x-y
1180 = x+7
3. Adding these equations together, you get
1980 = 2x.
4. Then divide, and x, the plane's speed, is 990 mph.
5. Replace x with 990 in one of the above equations and you get y of 190 mph for the wind speed.
