A bakery is preparing to ship an order of bagels. There are 15 bagels ready for delivery, and the baker is making 12 bagels every hour h. The order calls for 63 bagels. The equation below represents this situation. 15 + 12h = 63

Which number line represents the number of hours the baker will need to complete the order?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
