Writing expressions with variables
Learn to write expressions for more challenging phrases like "8 less than the product of 7 and x."
Now, let's practice!

How do you know what part to put first or last? It isn't specified.(10 votes)
You may put it in any order, but I would recommend that you write the expression with whatever comes first.
What I mean by that is this:
Suppose you have to write an expression from this description:
six added to the product of 4 and y
You can write it like this:
4y + 6
Or like this:
6 + 4y
Unless it is subtraction, you can write it in any order you choose. I like how the first answer sounds, but I would prefer the second answer because it is in the order that the question is written in, to double-check my work. But yes, you can do it any way you wish.(3 votes)
Why would adding and multiplying variables be helpful in every day life(0 votes)
You're going to a comedy club that has a fixed cover charge and a two-drink minimum. How much cash do you need to take with you?
Your truck has its fixed empty weight and is carrying a number of bags of concrete mix. Will you be able to drive over that rickety old wooden bridge?(2 votes)
what does it mean by eight less?(6 votes)
Eight less than a number means 8 subtracted from the number. So 8 less than x means x-8 (but not 8-x).(8 votes)
You would do if it says 8 less than 10 then put it at the end like 10+8 or 6 more than 7 then 7+6(6 votes)- How do you do it it’s very hard😩(4 votes)
what are you confused on? What part of the math?(4 votes)
- What if you get confused in the negative sign and the subtraction sign?(5 votes)
Q1: Write an expression that means "eight less than the product of seven and x".
can it not be written as 8-7x
?(2 votes)- Well, If you want 8 less than 7x, you take away 8 FROM 7x. The reason because if you want to take away 1 from 10, you would do 10-1 not 1-10.

when sal wrote the expression 4(2(7+2x)) can't he write,4(2(7+2x)? cant he take one parenthesis off?(2 votes)
brackets must be paired with each other. That is for each left bracket there must be a right bracket.(2 votes)
Hi, "the sum of six and the product of three and d" is (3 x d) + 6
Correct?
It said is was not(1 vote)
It likely doesn't like the "x". It would assume the X is a variable.
You need to write it as:3d + 6or3*d+6
The 1st version is better because it is the preferred format.(3 votes)
