We look for pairs of numbers in order to further simplify certain unsimplified square roots. For example, the square root of 20. From this, we pull out a 5 and two 2’s, Since there is a pair of 2’s, we carry one out, and since the 5 is not a pair, it stays inside of the radical. Therefore making it 2√5.
A better estimate would be something that is closer to one you had before...
Mary worked 22 hours.
To solve first you would subtract the amount she made in tips from her total earnings (317-185)
= 132
Then you divide that answer by her hourly salary of $6 (132/6)
=22
(B) FK and LJ
FK slope = (5-3)/(6-3) = 2/3
LJ slope = (2-0)/(8-5) = 2/3
