It is correct, but instead putting the word "ounce" after 1.50, put the word "pounds" after 1.50 instead. That would be the correct way of writing it. Other than that, you are correct!

Correct! 40 ounces is the answer to the first question.

Your answers are incorrect. First off, remember what Ms. Sue said above for the first answer post. "16 ounces = 1 pound 4 ounces = 0.25 pounds" First question: potatoes-----16 ounces - leave as is onions-------1.5 pounds-must convert into ounces-this is where you mad...

Yes 2 is the correct answer, when you put 2 in the equation, it checks out. 2(2) + 4(2) = 12 2 times 2 equals 4, and 4 times 2 equals 8. 4 + 8 = 12 12 = 12 So, yes 2 is again the correct answer.

No, x is not 3. If you were to put 3 as x in the equation, this would be what it looks like. 2(3)+ 4(3)=12 Obviously, you can tell that when everything is solved it does not equal 3 as x. 2 times 3 equals 6, and 4 times 3 equals 12. 6 + 12 = 12 18 = 12 So, 3 is not the value o...

The next thing that you do is combine like terms. For x, it is also 1x, it is the same value. So, once you do that you combine like terms. 1x + 3x + 6x = 10x Then, you have: 10x = 180 You then divide both sides by 10 to get the variable on the one side by itself. 10 divided by...

For the third step above that I said, the equation form should be like this: 448 - 448 + _ = 689 - 448 0 + _ = 241 _ = 241 241 is the blank, so then you double-check. 32 x 14 + 241 = 689 448 + 241 = 689 689 = 689 Hope this helps you again! :)

**MATHS**

Below should help: 32 x 14 +_ = 689 32 times 14 is 448, so you put that in. 448 + _ = 689 Next, you subtract 448 from 689 to get 241, and you subtract 448 from 448 to cancel out and leave just the blank on the left side. So, the blank equals 241, or the missing number for the ...

Yes, it is the answer. I have seen two ways of showing the final answer, so that is why I said 144.4. With my teachers, they wanted me to round the decimals without the 0. So, like with your answer of 144.40, they wanted me to say 144.4 instead. Both of them are the same value...

It can be either 144.40 or 144.4, but I recommend using 144.4 as the answer.
