She did answer the questions. I think that's what the = sign is that she put by each problem.
Please re-read what you wrote and fix it. It can't be "less four". That doesn't make sense.
Associative property, because the parenthesis are just moved around.
Commutative means you just switch the numbers around and get the same answer.

4(x^2-4x+3) You can factor this further by seeing which 2 numbers subtract to 4 (your middle term) and add to 3 (your last term). Post if you want it checked/need help.
I'm not positive, but I think you do it like this. Check my work based on your notes/textbook. 6C2=6!/(6-2!)2!=6!/4!2!=6X5X4X3X2/4X3X2X2=(cross out 4x3x2 on the top and bottom)=30/2=15

The noun is the person, place, or thing. The verb is the action.

Look at it this way: if you have money, it's a positive number and if you owe money, it's a negative number. You owe $4, you owe $9..do you owe money or have money? That tells you your sign. How much?

.83 is read as 83 hundredths because it goes up to the hundredths place. If you don't know this, study place value. So you re-write it as 83/100 and then simplify to 5/6.
Erica, did you see my post above? x+7+17=2x,x+24=2x, x=?
Do you see how ab+bc=ac? Then x+7+17=2x. Can you go from here?
It's quicker and it helps you get to a close answer.

You can use another variable there, such as x if you want. That's as far as you can get the equation with the information given.

A simple strategy would be to replace each option with groveling in the sentence above and see what makes sense. Quit ignoring, Lou! Of course I'll help you. That's the first one. Now try the rest.
keyboarding and word processing
Just keep typing random words and see if they continue to the next line or if you have to hit enter.
Reciprocal of 19/3 is 3/19. You just flip the fraction. To find a reciprocal of a whole number, put 1 underneath it and flip. Ex: 7=7/1, reciprocal=1/7.
What happens when you subtract x from both sides? It doesn't work. Plug in any number to see why. If x=1, then x+5=6. X always has to equal x and nothing else, so there are no solutions to this.
Since 3^5=243, set 2x+1=5 and solve.
1. Sorry, I was never good with radicals. 2. 7x-3=4x+9 You want to get the variables (letters) on one side and numbers on the other. Add 3 to both sides: 7x=4x+12 Subtract 4x from both sides: 3x=12 Divide both sides by 3: x=? 3. 12-4x=x^2 x^2+4x-12 Now factor it. You are looki...

You're very close but you left out one thing. You have to divide to find averages, so: (99+91+85+x)/4>=90 99+91+85+x=360 Take it from here.

Rewrite the problem. It makes no sense. What are the symbols between the 9 and 3 and the 3 and 4?
Yes, you are right.
I think you would then multiply that by 2, since it says to expect double production..?
Multiply either or both equation(s) to eliminate either the x's or y's. In this cas, multiply the top by 3 and the bottom by 2 to eliminate the x's. -6x+15y=42 6x+4y=34 The x's cancel and you add what's left. 19y=76 y=? Then put y back into either ORIGINAL ...
