There is 168 hours in 7 days
There is 144 hours in 6 days
144-42=102
He is not at work for 102 hours on a 6 day week, I think.
Well we know the 45 is a constant so B and C are marked out which leaves us with A and D. Now we know that Lydee's mom has saved up 250 so she can't spend more than 250 dollars so it would be D
Answer: D
Hope I could help
first we have to find the slope Y2-Y1/ X2- X1
7-(-1)=8
5-(-4)=9 slope= 8/9
Poin slope form ------- Y-Y =M(X-X)
Y+7= 8/9 (X+5) or
Y-1= 8/9 (X-4)
(12 2/3) divided by 8 = 19/12 or 1.58333333333333
Maybe it all of them the obtuse looks wrong but if you look at it by the bottom right it's more than 90*degree
