Question

write the phrase as a mathematical expression. 9 more than 4 times a number

Answer 1

9 + (4 x y) 
because it is 9 + 4 times any number (y,x,z)

Answer 2

Hello,


"9 more" is saying "9 +"

"4 times a number" is like saying "4x", you don't know what that number is, so you replace it with a variable "x". 

Let's put it together: 9 + 4x

There you go! Hope this helps =).
