Answer:

it would be d 60t

Step-by-step explanation:

Lea and Marie are washing all the windows in their house. It would take Lea 80 minutes to wash the windows by herself, and it would take Marie 60 minutes to wash them by herself. Lea creates a table so she can find out how long it will take to wash the windows if they work together. What is the missing value in the table that represents the rate for Marie?

A table showing Rate in part per minute, Time in minutes, and Part of Windows Washed. The first row shows Lea, and has StartFraction 1 Over 80 EndFraction, t, and StartFraction 1 Over 80 EndFraction t. The second row shows Marie, question mark, t, and StartFraction 1 Over 60 EndFraction t.

so if she and her friend would be washing all of the windows in their house then their house is 60 cm and 60 in so the answer would be 60t

<span>The missing value that represents the rate for Marie is 1/60. As mentioned in the table, rate (r) is the part (p) per minute (t). Let's check if it works for Lea. If p = 1/80t, then r = (1/80t)/t = 1/80 * t/t = 1/80 * 1 = 1/80. So, the formula works. Now, calculate the rate for Marie. If p = 1/60t, then r = (1/60t)/t = 1/60 * t/t = 1/60 * 1 = 1/60</span>

What's the answer for X?

We know all these angles combined equals 360, so:

3x + 20 + 3x + 20 + x + x = 360
8x + 40 = 360
8x = 320
x = 40

Hope this helps!
