Answer:
B
Step-by-step explanation:
26 letters 10 numbers no repeating
P(26,2)×P(10,4)
=26×25×10×9×8×7=3276000
-- The smallest 6-digit whole number is 100,000 .
-- The largest 4-digit whole number is 9,999 .
-- The difference is (100,000 - 9,999) = 90,001 .
No 2 numbers do this.
Possible numbers that can multiply to 108:
<span>1 x 108 = 108
2 x 54 = 108
3 x 36 = 108
4 x 27 = 108
6 x 18 = 108
9 x 12 = 108
12 x 9 = 108
18 x 6 = 108
27 x 4 = 108
36 x 3 = 108
54 x 2 = 108
108 x 1 = 108
Possible numbers on that list that when subtracted equate to 6:
None</span>
Answer:
(A), (C) and (D).
Step-by-step explanation:
An equation will have infinite solutions if both sides of the equal sign are the exact same thing, for instance
. (You can test this with any value of x and find that they all work!)
So to find the equations that have infinite solutions, we need to see which have the same exact sides.
have the same thing on each side:
, so this has infinite solutions.
does not have the same thing on each side, so it doesn’t have infinite solutions (it has 1)
has the same thing on each side:
, so this has infinite solutions.
And finally,
has the same thing on each side:
, so it has infinite solutions.
Hope this helped!
