Answer:

-1=x

Step-by-step explanation:

You multiply the -3 into the (2-x). which gives you -6+3x=9x. Know you wanna get ride of the 3x so you subtract from both sides, which then gives you. -6=6x. From here were gonna need to get x by itself so you divide both sides by 6.

Karyn proofreads 15 pages in 2 hours for $40. What is her proofreading rate in pages per hour?

vladimir1956 [14]

Hey there,
2 hours = 15 pages
1 hour = 15 / 2
= 7.5 pages
15 pages = $40
1 page = $40 / 15
= $2.666666666666667
7.5 pages= $2.666666666666667 x 7.5
= $20

Hope this helps :))

I’m another normally distributed test score is 80 and the standard deviations is 10. How common are values in the less than 60?
