Solve the top two please

1.. 1/5 (9k + 12) = 15

Answer- K = 7

2... Felix paid for 11 months

Solution:

Given that Felix joins a local recreation center to play basketball

Annual fee = $ 20

additional fee per month = $ 15

Felix pays writing a check for $ 185

To find: Number of months for which Felix prepaid

From the given information, we can frame an equation as:

amount paid = annual fee + additional fee (number of months )

Let "m" be the number of months for which felix paid

Therefore we get,

amount paid = annual fee + ( additional fee x m)

185 = 20 + 15(m)

185 - 20 = 15m

15m = 165

m = 11

Thus Felix paid for 11 months

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)
