The answer is c) 9.

The value of 9 nickels is $0.45. If there are 9 nickels, there are 8 dimes left over. The value of 8 dimes is $0.80.

Simply add the numbers together to get the total worth: $0.45 + $0.80 = 1.25.

Therefore, the answer is C. I hope this helped!

70,000 + 6,000 + 800 + 30

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
