Answer: C. 2520


Step-by-step explanation:

Given digits: 0, 1, 2, 3, 4, 5, 6

Total number of digits=7

The number of ways, in which 5-digit numbers can be formed using the above digits if repetition of digits is not allowed is given by permutation:-

^7P_5=\frac{7!}{(7-5)!}\\\\=\frac{7\times6\times5\times4\times3\times2!}{2!}\\\\=\frac{5040}{2}\\=2520

Hence, the number of 5 digit numbers can be formed with the given digits (if repetition is not allowed)=2520

Phantasy [73]

Answer:

84

Step-by-step explanation:

12*3+6x=4.20(12+x)

36+6x=50.4+4.2x

6x-4.2x=50.4-36

1.8x=14.4

x=14.4/1.8

x=8 pounds of cashews is used.

Proof:

12*3+6*8=4.2(12+8)

36+48=4.2*20

84=84

Label the parts of the equation 4x6=24
Alisiya [41]

The numbers are constants, and the multiplication symbol is an operator.

If this equation were 4x * 6 = 24, then 4 would be a coefficient and x would be a variable. 6 and 24 are still constants and the multiplication symbol is still an operator.
