Answer:c
15x - 4
Step-by-step explanation:
15x - 4
Answer:
.278
Step-by-step explanation:
There are 9 coins
P (nickel) = number of nickels/ total
= 5/9
Keeping the coin
We now have 8 coins, 4 nickels and 4 dimes
P (nickel) = number of nickels/ total
= 4/8 = 1/2
P(nickel, keep, nickel) = 5/9* 1/2 = 5/18=.2777777777
Consider this option:
1. rule: the equation will be the same if the both its parts are multiplied by one number ('0' is not included!).
2. using the rule, described upon:
-3x-2y=-7 (*(-1));
6x+4y=14 (*2);
-6x-4y=-14 (*(-2)).
Note, that not all the ways are described.
The pattern is in threes so all you have to do is simply add 3 to 21 and so on and so on
Answer:
36
Step-by-step explanation:
a = (2×3) = 6
b = (3×2) = 6
Substitue into the equation:
a×b=ba−ba+ab
= 6×6 - 6×6 + 6×6
= 36 - 36 + 36
= 36
Therefore, (2*3)×(3*2) = 36
Hope this helps.☺
