Karl wants to rent a bike for at most $55. He can rent a bike for $7 per hour plus a $9.50 flat fee. Any portion of an hour is c
Papessa [141]
Answer 6 hours
Reason
7x + 9.50 = 55
-9.50. -9.50 subtract from both sides
_____________
7x = 45.50

Divide both sides by 7 to isolate x
X = 6.5
So he can rent for 6 hours (the .5 would be charged as a full hour per the problem)

A quadrilaterals consecutive angles measure (3x+10), (9x+50), (4x), and (13x+10). Determine the value of x.
LuckyWell [14K]

The value of x is 10

Step-by-step explanation:

We know that the sum of internal angles of a quadrilateral is 360 degrees

So,

Given

Angle 1 = A1 = 3x+10

Angle 2 = A2 = 9x+50

Angle 3 = A3 = 4x

Angle 4 = A4 = 13x+10

So,

A_1+A_2+A_3+A_4 = 360\\(3x+10)+(9x+50)+(4x)+(13x+10) = 360\\3x+10+9x+50+4x+13x+10 = 360\\3x+9x+4x+13x+10+50+10 = 360\\29x+70 = 360

Subtracting 70 from both sides

29x+70-70 = 360-70\\29x = 290

Dividing both sides by 29

\frac{29x}{29} = \frac{290}{29}\\x = 10

Hence,

The value of x is 10

Ethan sold some watches at $14 each and 20 bookmarks at $1.50 each. Roy sold the same number of watches at $13.50 each and 20 bo
-Dominant- [34]

[<Answer>] (1):
<em>Heyy there, it's Avery. And I'm here to help! :)

</em>----------------------------------------------------------------------------------------------------------[<The Explanation>]:

Let x= number of watches sold

<em>Ethan= x(14) + (20)(1.50)</em>

<em>Roy = x(13.50) + (20)(1.80)</em>

Since they collected the same amount of money:

<em>14x + (20)(1.50) = 13.50x + (20)(1.80)</em>

Combine like terms:

<em>14x - 13.50x = (20)(1.80) - (20)(1.50)</em>

<em>0.50x = 36 - 30</em>

<em>0.50x = 6</em>

<em>x = 6/0.50</em>

<em>x= 12</em>

Ethan sold 12 watches. And also Roy.
Andddd...We're done! :D

----------------------------------------------------------------------------------------------------------
[<Ending>] <3

<em>Hope this helps and if it's wrong, you can't sue me! :D</em>

Bye! Hope this works for you :)

Have a nice day! - Avery <3
