Answer:
9) e=-40 10) k=9
Step-by-step explanation:
9) e/4-10=-20 add 10 on both sides
e/4=-10 Multiply everything by 4
e=-40
10) 0.4k-4+1.6k=14 combine like terms
2k-4=14 Add 4 on both sides
2k=18 divide both sides by 2
k=9
Problem 1
Answers: Choice A, choice D
The formula you use is
a & c/d = (a*d+c)/d
To convert from mixed number form to improper fraction form.
So,
6 & 2/3 = (6*3+2)/3 = (18+2)/3 = 20/3
And also,
8 & 1/5 = (8*5+1)/5 = (40+1)/5 = 41/5
