Answer:
value of x = 24°
Step-by-step explanation:
here's the solution,
the given pair of angles are co-interior angles, and their sum = 180°
so,
=》3x - 1 + 4x + 13 = 180
=》7x + 12 = 180
=》7x = 180 - 12
=》x = 168 ÷ 7
=》x = 24°
We already know that the hourly rate for John is : 1/6 and the hourly rate for Rick is : 1/8. What we don`t know is a hourly rate for Molly and we will call it 1 / x.
The hourly rate for all together is: 1 / 3
An equation is:
1 / 3 = 1 / x + 1 / 6 + 1 / 8
1 / 3 = 1 / x + 4 / 24 + 3 / 24
1 / 3 = 1 / x + 7 / 24
1 / x = 1 / 3 - 7 / 24
1 / x = 8 / 24 - 7 / 24
1 / x = 1 / 24
1 / 3 = 1 / 24 + 1 / 6 + 1 / 8
The hourly rate for Molly is 1 / 24. Molly can paint the room alone for 24 hours.

Explanation: I’m pretty sure you’re looking for the perimeter. Therefore, since you have a rectangle, you’ll have 4 sides. The measures are 100 by 140 so you’ll put 100 and 140 on the other sides and simply add them up.
