Answer:

21 minutes

Step-by-step explanation:

Ms.Keller is speed reading a book that has 342 pages, she has already completed 300 of them and can read 2 pages per minute. The question is asking how long it'll take her to finish this book.

So we know the vital information that Keller reads two pages per minute and she only has 42 pages left of the book, this is all we need to answer the question.

All we need to do is divide 42 by 2 :

42 / 2

21

Therefore, it'll take Ms.Keller 21 minutes to finish the book at the constant speed

6. If X is the midpoint of WY, WX = 3x - 1 and<br> WY = 10x - 26, find XY.
Dennis_Churaev [7]

XY = 17

Step-by-step explanation:

It is given that x is the mid-point of WY, so it divides WY in two equal parts

WX and XY so the sum of both lengths will constitute the length of WY

WY = WX+XY\\XY = WY - WX

putting values

XY = 10x-26 -(3x-1)\\= 10x-26-3x+1\\= 7x-25

As X is the mid-point,

WX = XY\\3x-1 = 7x-25\\3x-1-3x = 7x-25-3x\\-1 = 4x-25\\-1+25 = 4x-25+25\\24 = 4x

Dividing both sides by 4

\frac{4x}{4} = \frac{24}{4}\\x = 6

XY = 7x-25

=7(6) -25\\= 42-25\\=17

So,

XY = 17

<u>Verification:</u>

WX = XY

3x-1 = 7x-25\\3(6)-1 = 7(6)-25\\18-1 = 42-25\\17 = 17
