Which expression is the correct translation of the following word phrase?
Llana [10]
Hey, there! 

The parentheses would make it multiplication 
The word sum means add 
A number was unknown, so we will label it as "x" 

So, let's see what we're working with here! 

If you chose "Option A" the question would be "five multiplied by a number and the sum of 3" (that doesn't give you the right answer" 
For B. same thing with option A 
For "Option C" its not asking you "a number with sum of three times five" 

So, this leaves "Option D." as your answer because 3 is getting multiplied by the sum of some number and five

Good luck on your assignment and enjoy your day!

(28x+2x+-x)+(-12+-4)

29x+-16

= 29x-16
