Use pemdas 12 x ( 13 - 9 ) / 6 write 3 steps

   8

Step-by-step explanation:

p (parenthesis)

e (exponents)

m/d (multiplication or division)

a/s (addition or subtraction)

steps

12x(13-9)/6

12x4/6

12x4=48

48/6

8

this is 5 steps but it still works

8

Step-by-step explanation:

We know PEMDAS stands for Perenthesis Exponents Multiplication Division Addition Subtraction. So, first solve the equation in parenthesis; 13-9=4. Then you have 12x4/6. Next, multiply 12 by 4; 12x4=48. Then you have 48/6. 48/6 is 8. So, the answer is 8.  

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
