8•(-0.25) would be -2 if that's what you're asking :)
What we know:
a, b and c are not zero
abc=c
What we need to find:
a
abc=c
abc/bc=c/bc additive inverse
a=1/b simplified
5 shirts for $21
the 6 deal would be $4.25 for each shirt
4 deal would be $4.50 for each shirt
and the 5 deal is the cheapest because its $4.20 for each shirt
Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
2 number cubes, which i'm assuming are dice, = 6^2, which = 36. The number of odd digits = 3, the number of even digits = 3. There are 18 odd totals and 18 even totals out of 36 outcomes, or 18/36, or 1/2.
