What do you have to divide by to get from 60 to 50??

Answers

60:50=(60)/(50)=(6)/(5)=\boxed{1(1)/(5)\ or\ decimal\ form\ 1(1\cdot2)/(5\cdot2)=1(2)/(10)=1.2}

I don't know.  Let's calculate it together:

60 divided by (the number) = 50

Multiply each side by (the number) :

          60 = (the number) x 50

Divide each side by  50 :

         60 / 50 = The number

         60/50 = 6/5 = 1.2

NEED help plz!

Answers

So since the problem says the number 46 is equal to something, you immediately know that your equation will look like this

46 = something

Now, when an unknown number is multiplied by a number, it has the number and a letter right next to it.

example.  23p

So since 23p = 46, your answer is B :) Hope this helped!
it's B because p is used as the unknown number here and some ways of saying multiplication is
23 x p
23 (dot in the middle) p
or 23p
since the qw says the number 46 is equal to it is
46=
so the answer is B) 46=23p

Suppose that on a coordinate plane a hexagon is reflected across the x-axis. Compare the area of the original hexagon to the area of the transformed figure. Justify your answer. A) The areas may or may not be the same because the scale is not given. B) The areas are equal. A reflection is a rigid transformation, which does not change the size of the original hexagon. Therefore, the area is preserved. C) The area of the original hexagon is greater than the transformed figure. A reflection decreases the size of the original polygon. Therefore, the area is not preserved. D) The area of the transformed hexagon is greater than the original figure. A reflection increases the size of the original polygon. Therefore, the area is not preserved.
