30% of the days in November were sunny how many days were sunny

9 days of November were sunny.

Step-by-step explanation:

There are 30 days in November, so all we have to do is 30% of 30.  After the equation is solved, you should get 9.

9 days

Step-by-step explanation:

There are 30 days in November.

30% is the same as .3.

Take 30 times .3.

30 x .3 = 9

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
