Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.
I wrote that wrong, sorry.
Well the angles should all equal 360. Since you know 90 and 160 then 360-90-160=110. Angle 2 is 90* so 110-90=20 so angle 4 is 20. Angle 2+ angle 4: 90+20=110 or C :)

Hi,
Start with 6b-27=3(5b-2)
then add 27 to each side, 6b-27+27=15b-6+27
next simplify, 6b=15b+21
now subtract 15b from both sides, 6b-15b=15b+21-15b
simplify again, -9b=21
divide both sides by -9, -9b/-9 = 21/-9
answer: -7/3
Have a great day!
