Baker sold 8 cakes. If he had made 40 cakes initially how many more cakes did baker make than those he sold?
Let's denote the number of cakes that Baker made initially by x. Then he sold 8 cakes and the number of cakes remaining is x-8. 

The number of cakes that Baker made in total is x. The number of cakes that he sold is 8. Therefore 

x-8=40. 

Therefore the answer (numeric) is: 

x-8=40 

x=48


Q: If the length of a rectangle is 5 times its width and the perimeter of the rectangle is 62, what are the dimensions of the rectangle?

A: Let's think step by step. Introduce intermediate variables and solve the task symbolically. 

Let's denote the width of the rectangle by w. Then the length of the rectangle is 5w. 

The perimeter of the rectangle is the sum of the lengths of all four sides. Therefore 

5w+w+5w+w=62 

12w=62 

w=62/12=5.16667 

Therefore the answer (numeric) is: 

w=5.16667, 

l=5*5.
