25 because $518 ( their total ) divided by $21 ( the amount for EACH uniform) is 24.6 which isn’t possible so round it to 25
(5+22)x(35-27)+6x6
27 (35-27)+6x6
27x8+6x6
27x7+36
216+36
=252
Answer:
11/20 or 99/180 days
Step-by-step explanation:
55/100 converted to ?/180

26.
The domain is {-8, -5 and 7} so it cannot be a or b.
A function is either a one-to-one or a many-to-one relation
Look at option d . The -8 in the domain maps on to 2 elements in the range
(-6 and 1) so its a one-to many relation and its NOT a function.
