1. 1,2,3 ok
#4 no idea -- no statement given
5-8 ok
#9 ok, but you should have written (9x-6)/3
10 ok
#11, ok but 5/(x-z)
#12 ok, but why not just say y/6 ?
13 ok
#14. √(1/144) = 1/12
√1/144 = 1/144
be specific on just what is under the √
#15 nope. B would be
k(mp) = k(pm)
or
k(mp) = (mp)k
#16. again, parentheses are important
u/z+xy squared, for u = 20, x = 4, y = 7, and z = 10
u/z + (xy)^2 = 20/10 + 28^2 = 786
(u/z + xy)^2 = (2+28)^2 = 900
Other arrangements are possible, but they do not end in integer answers
How did you get B?
17 - nope. D is 6-(-3)
18 ok, but what's with the "end fraction" stuff? 6/9 not clear enough?
19,20 ok
#21
12[62 ÷ (52 – 42) + 4]
12[62/10 + 4]
12[10.2]
122.4
You must have a typo
#22. nope
#23. Nope - subtract the total yards already run: 78-(7+5) = 66
#24 A
25,26 ok
