C. Because the full length is 44. Now the equation is 6x-5=44. Add 5 to both sides. 6x=49. 49/6= 8.16666666666 so you round and get 8.17
4 1/6 = 4 7/42
2 4/7 = 2 24/42
2 24/42 + 4 7/42 = 6 31/42
6 31/42 = 283/42
83, 89, and 97 are three primes between 80 and 100.
The primes between 30 and 50 are 31, 37, 41, 43, and 47, all of which are odd. All other numbers between 30 and 50 are composite.
To mentally find 2*50*25, you could either first multiply 25 by 2, to get 50*50, which can easily be calculated as 2500, or you could multiply the 50 by 2, for a result of 100*25, which is clearly also 2500.
I got 1.5 I used Siri and then calculated tried to see if items correct so I went on safari and found nothing so I this it would be either a or c
Goodluck
