It depends what number you're dividing by..
if it were 278 you would divide by 9 and have 8 left over.
(i think this is correct)
There are many ways, but here is one:
x = 100
Since ‘x’ is 100 and we want 100 more, we just need to add ‘x’ to 623
Answer: x + 623 (Make sure you define your ‘x’ value)
Answer: b. 6(x + 4)
Step-by-step explanation:
The given word phrase = the product 4 more than x and 6
where , 4 more than x is equivalent to 
Therefore the algebraic expression for the given word phase "the product 4 more than x and 6"
=

Hence b. is the right option.
The algebraic expression for the given word phase is
