Answer:3aC +bC
Step-by-step explanation:
The ans shld be b blah blah
total book =1
1/5 + 2/3 + wed = 1
get a common denominator of 15
1/5 * 3/3 + 2/3 * 5/5 + wed = 1 * 15/15
3/15 + 10/15 + wed = 15/15
combine like terms
13/15 + wed = 15/15
subtract 13/15 on each side
wed = 15/15-13/15
wed = 2/15
He read 2/15 of the book on Wednesday
1 hour = 60 minutes
Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes
Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.
Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.
Hope this helps!
Answer:
x=2
Step-by-step explanation:
logx (2x)^3 = 6
We can rewrite without the exponent
3 logx (2x) = 6
Divide by 3
3/3 logx (2x) = 6/3
logx (2x) = 2
Raise each side to the base x
x^ logx (2x) =x^ 2
2x = x^2
Subtract 2x from each side
2x-2x = x^2 -2x
0 = x^2 -2x
Factor an x
0 = x(x-2)
Using the zero product property
x =0 x-2 =0
x =0 x=2
We cannot have a base of 0, so x cannot equal 0
x=2
