Answer:
Person A paints the house in 12 days.
person B paints the house in 60 days.
Step-by-step explanation:
The together rate is the sum of each separate rate.
Person A can paint the neighbor's house 5 times as fast as Person B.
This means that the rate of person A is 1/x, and the rate of person B is 1/5x.
The year A and B worked together, it took them 10 days.
This means that:
![\frac{1}{x} + \frac{1}{5x} = \frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%20%2B%20%5Cfrac%7B1%7D%7B5x%7D%20%3D%20%5Cfrac%7B1%7D%7B10%7D)
Multiplying everything by 10x
![10 + 2 = x](https://tex.z-dn.net/?f=10%20%2B%202%20%3D%20x)
![x = 12](https://tex.z-dn.net/?f=x%20%3D%2012)
This means that:
Person A paints the house in 12 days.
person B paints the house in 60 days.
Answer:
1120 in³
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = area of base × height , then
V = 80 × 14 = 1120 in³
Olate the variable by dividing each side by factors that don't contain the variable.

Answer:
Step-by-step explanation:
The formula F = 1.8C + 32 can be used to find the temperature in degrees Fahrenheit F when the temperature is given in degrees Celsius C. For what value is the temperature in degrees Fahrenheit equal to the temperature in degrees Celsius? Justify your reasoning by writing and solving an equation. (Hint: If Fahrenheit and Celsius are equal, they can be assigned the same variable.)
