The wind blew away 30 of your muffins. That was 5/6 of them! How many are left?

6 muffins

Step-by-step explanation:

lets say we have 5 over 6 equals 30 over x(the unknown number)

to get from 5 to 30 you multiply by 6.

so multiply 6 by 6 and you get 36.

then do 36-30. that equals 6.

the answer is 6

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
