Answer:
The amount of white paint Jen used to paint the walls in her room is:
Step-by-step explanation:
To solve the exercise you only have to pay attention to the statement, in the section that says that 4/5 parts of the total painting is blue, therefore, if 1 is the total painting, you must do a subtraction:
Since the remaining white paint is 1/5 of the total, you have two ways to solve the exercise: multiply the total paint (8.2 pints) by 1/5 or divide the number by 5, as shown below:
- <u>Amount of white paint = 8.2 pints * (1/5) = 1.64 pints.
</u>
- <u>Amount of white paint = 8.2 pints / 5 = 1.64 pints.
</u>
As you can see, the two methods provide a <u>value of 1.64 pints, which corresponds to 1/5 of the total paint and is the amount of white paint used</u>.

Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
Using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A (- 2, 4 ) and (x₂, y₂ ) = P (2k, k)
AP = 
Repeat
with (x₁, y₁ ) = B (7, - 5) and P = (2k, k)
BP = 
Given that AP = BP, then
=
Square both sides
(2k + 2)² + (k - 4)² = (2k - 7)² + (k + 5)² ← expand factors on both sides
4k² + 8k + 4 + k² - 8k + 16 = 4k² - 28k + 49 + k² + 10k + 25
Simplify both sides by collecting like terms
5k² + 20 = 5k² - 18k + 74 ( subtract 5k² from both sides )
20 = - 18k + 74 ( subtract 74 from both sides )
- 54 = - 18k ( divide both sides by - 18 )
k = 3
