Thanks for making my day !!!
1. 4 aces and 26 – 2 (aces) red cards…so 28 out of 52
28/52= 7/13 answer b
2. prob of picking 2 green…
5 out of 20 or 1/4 each time, so 1/16…now you want not both, so that would be 15/16 but that isn’t a choice so…umm….are there only 20 marbles in this bag? me be confused and it is late…let me continue
3. 240 miles/ 20 miles = 12 so 12 inches d
4. 16/4d +2 = 8/3
ok…is this 16/ (4d+2)?
so cross multiply…
16(3) = (4d+2)8
48 = 32d + 16
32 = 32d
1= d
or you can say that to get from 8 to 16 you multplied by 2, so to get from 3 to what number you multiply by 2? that would be 6 so 4d+2 = 6 and d=1
now…that wasn’t an answer choice so maybe that is not the intended proportion. hmmm….let me think some more…
i think it is time for me to go to sleep…i can’t even get these right!!! unless i misread your questions…as there are no choices for some of my answers!
good night!
