Answer:
$16.80
Step-by-step explanation:
12 * 1.4 = 16.8
Ok, hmm
possible ones are
starting with 8 or 9
adds to 13
8+5=13
9+4=13
thepossible numbers are 85 and 94
tens is 3 more than ones digit
8-5=3 true
9-4=5, not what we looking for
aswer is 85
Answer:
5/16
Step-by-step explanation:
Each number can happen in exactly one way (one sets the digit of tens and the other of ones).
We know that the law of divisibility by 3 is "sum of digits has to be divisible by 3", so let's examine the numbers:
11
13
15 - Yes
17
31
33 - Yes
35
37
51 - Yes
53
55
57 - Yes
71
73
75 - Yes
77
So it's 5 out of 16 options.
We could do it by examining the relation and modulus shifts with each digit, but for 16 numbers it's seriously faster to just list them.
Y= +9
0+9=9
2+9=11
4+9=13
6+9=15
