question: 3 of 60
a phone company charges customers a monthly charge using the equation c = 40 + 0.3m, where cis the monthly
charge, in dollars, and m is the number of minutes ed by the customer. if someone's monthly charge is $46, how
many minutes did the person use that month?

20 minutes

Step-by-step explanation:

The monthly charge(C) of the customer is represented by:

C = 40 + 0.3m

where m is the number of minutes used by the customer. We need to find how many minutes did the customer use if the bill is $46. For this we substitute 46 in place of C and find the corresponding value of m.

So,

46 = 40 + 0.3m

46 - 40 = 0.3m

6 = 0.3m

6/0.3 = m

m = 20 minutes

This means the person used 20 minutes which makes the bill equal to $ 46

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✌✌✌
