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 hours?

Answers

Answer 1
Answer: 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.

Answer 2
Answer:

Final answer:

As per the given values, Eduardo rented the bike for 5 hours.

Explanation:

Fixed cost = $19

Total amount paid = $49

Cost of each hour = $6,

Finding the number of hours Eduardo rented the bike for -

= Total amount paid - fixed cost

= 49 - 19

= 30

This remaining amount represents the cost of the hours rented.

Calculating the number of hours -

= Total number of hours /  Cost of each hour

= 30/6

= 5

So, Eduardo rented the bike for 5 hours.

The height of a box is 7 inches. Its length is 6 inches more than its width. Find the length if the volume is 280cubic inches.

Answers

h = 7
l = w + 6
V = 280

V = lwh

Plug in what we know:

280 = (w + 6)(w)(7)

Distribute W into the first parenthesis:

280 = (w^2 + 6w)(7)

Distribute 7:

280 = 7w^2 + 42w


Divide 7 to both sides:

40 = w^2 + 6w

Subtract 40 to both sides:

w^2 + 6w - 40 = 0

Factor:

(w - 4)(w + 10) = 0

Therefore, w = 4.

Plug this back into the equation for the length:

l = w + 6

l = 4 + 6

l = 10
Volume=Length*Width*Height \n 280=(x+6)*x*7 \n 280=7x(x+6) \n 280=7x^(2)+42x \n 0=7x^(2)+42x-280 \n  0=7(x^(2)+6x-40) \n 0=7(x+10)(x-4) \n Since\ we\ can't\ have\ negative\ values,\ x=4 \n Width=4 \n Length=Width+6 \n Length=4+6 \n \boxed{Length=10}
