Thanks for sharing! Did anyone notice it says Donder instead of Donner? lol.
What's 5 *6x? What's 5 * 9? Remember to separate the two terms with the plus sign.
Just divide it out. 8/11=.727272 etc = .73
5th grade math
Inverse operations are like "opposites", what undoes the operation. Multiplication and division are inverses, as are addition and subtraction. For example, if you have 4x+2=10, you have to use the inverse of addition (subtraction) to get rid of the 2. 4x+2=10 ...
Tyler, I did one of these for you yesterday. You should be able to do them on your own now. Don't post any more of these problems without attempting them yourself (and showing work) first!
What are you asked to do with this?

He/she needs a multiplication story, not a division story. 5 classmates each have 2 pencils. How many pencils do they have in all? 5 * 2 = 10 pencils
There are two factors in that sentences, the 9 and 4.
At the mall, you spent a total of $170.86. You bought 2 pairs of jeans for $ 39.95 each,a jacket for $45.99, and shirts for 14.99each. How many shirts did you buy? jeans=$79.90 jacket=45.99 total cost so far=125.89 170.86-125.89=$44.97 14.99x=44.97..solve for x, that's ...
Yes. If the groups were equal, you could multiply them to get the answer quicker. Since they are unequal, you can only add.
Where was this when I was in school?? LOL.
Aims math [help please very appreciated]
15x+4=21+2x Subtract 2x from each side. 13x+4=21 Subtract 4 from each side. 13x=17 Divide each side by 13. x=17/13
9 1/8 - 2 5/8 Since you can't do 1/8-5/8 because you can't do 1-5, you have to "borrow".. 9 1/8 becomes 8 9/8...if it was just 9 it would be 8 8/8 because 8/8=1..so it's 8 9/8 8 9/8-2 5/8=?

That's not what he's referring to, Gabby. David, that means out of 25, pick 8. I forget how to solve these though, so hopefully someone else will respond.

The responses were not by the 3rd grader, only the question was.

(11+12+5+3+x)/5=7.4 31+x/5=7.4 Multiply both sides by 5 31+x=37 x=6
Yes, there is a common between yes, ma'am. No, I don't think it's necessary to say that. I think it's a bit old school. There are other ways to show respect besides that.
x=2y y=2x+3, y=2(2y)+3 y=4y+3 Solve that and then replace it to solve for x. You can post your answer if you want it checked or need more help.
3/8+y=-3/16 y=-3/16-3/8 y=?

Yes, that will actually be a right triangle. You can do the pythagorean theorem to check it.
1/2x+1/3y=5 1/4x+1/3y=4 First I want to get rid of the fractions..multiply the first equation by 6 and the second one by 12. 3x+2y=30 (1) 3x+4y=48 (2) Now multiply the first equation by -1. -3x-2y=-30 3x+4y=48 Add the equations together. 2y=18 Solve for y, put it back into (1...

I don't think you just multiply the numbers for this one. If the question said that he was going to all 4 office stores, all 4 electronic stores, all 8 clothing stores, and all 5 sporting goods stores and asked how many ways can he do that, then you would multiply them all...
What number? I would guess A since it's a set of ten and could've been rounded, but cannot tell without seeing the number.
3, 6..They are increasing by 3 Bottom row is decreasing by 4
Algebra one :)
To rewrite in Ax+By=C form, rearrange the terms so that x and y are on the left and the number is on the right. 5y-6=2x+3 Subtract 2x from both sides. -2x+5y-6=3 Add 6 to both sides. -2x+5y=9
You can't solve that unless you have more information that you forgot to include.

The coefficient of kinetic friction for a 22 kg bobsled on a track is 0.20. What force is required to push it down a 6.0° incline and achieve a speed of 70 km/h at the end of 75 m?
Right. So what's 120 minutes from 3:00?

All negatives would be negative, all positives would be positive, a positive and 2 negatives would be positive, 2 positives and a negative would be negative..

what is something i would find on commissioners court AGenda and not in city council court agenda?
That's what I'm thinking. It should work if you make the left and right sides the same and the top parts of "the house" the same. You can make the left and right both 5, and all other parts 2.
To tell how long it would take you, I would say it aloud just like you would for the exam and time yourself. You could also have someone else time you. I would do this at least twice.
Two negatives make a positive, and 20/10=2, so your answer is 2.

You can't do anything with that..

8.23 * 10^7 82300000 The exponent tells you how many times to move the decimal. If it's positive, you move it to the right. If it's negative, move it to the left. Example: 8.23 * 10^-7=.000000823

Pentagons are five sided figures, in which each of the five sides are equal. To figure out the perimeter, you take the side given and multiply it by 5 since each side is the same. I'll do the first one for you and you can do the rest. 6 * 5 = 30.

What are you talking about?
8.5>6.1+0.6y Subtract 6.1 from both sides 2.4>.6y Divide both sides by .6 4>y or y<4 To graph this, find where y=4, and draw a line across this point. Since y<4, you will then shade below the line.
The angles with measure the same..the side lengths and perimeter will be comparable by ratio.
