You can use place value because that will tell you what place it is in and will make it much more easier
then you want to do 3.14 x 17×17 = .... then add them both and you got the area
Y - 18 = (30 - 18)/(5 - 3) (x - 3)
y - 18 = 12/2 (x - 3)
y - 18 = 6(x - 3) = 6x - 18
y = 6x
The constant of variation (k) is 6.
10*0.2=2 When you are multiplying a decimal by 10 you just take off the decimal and you have the answer 2
Answer:
x=27
Step-by-step explanation:
3=x/9
9*3=(x/9)*9
27=x
x=27
Multiply by 9 on both sides to get the x by itself because x(1/9)*9=x, and when you do something to one side of the equation you also have to do it to the other side.
