—4 and -5= -9 then 8p-6p=2p and 2p+20p= 22p-9
Hi.
So to solve this first you have to do 1.60 or 1.6 times 6= 9.6 or 9.60.
Everything costed 24.60.
24.60 minus 9.60=15
There are 6 pendants so 15/6= 2.5.
So each pendant costed 2.5
$10d ≥ $800 Your answer is D
[they get $10 per donation(d), and they need at least $800 (that is the minimum, so they can raise more than $800).]
Step-by-step explanation:
by considering how many inches (") are in one foot (').
the answer is 12. there are 12 in in every ft.
so, now we can convert everything to the smallest scale (inches) and do the calculation based on inches :
(8×12 + 4) - (2×12 + 6) = 96 + 4 - 24 - 6 = 100 - 30 = 70"
and now to translate 70" back into ft and in :
70/12 = 5 with a remainder of 10
70" = 5' 10"
