Any help on the correct way to read these problems would be appreciated and why 13+7=20 isn’t correct.

I’m not understanding how these problems are supposed to be interpreted.

Do you only look at one side and not the whole picture?

I don't know, but to me this problem doesn't give enough info for me to solve, although I could just be missing something, any step by step guides would be appreciated.

For the attempt shown we are only able to edit the box in orange, the other two numbers we can't change.

My daughter’s homework asks to compare the underlined digit to the circled digit. None of the answers seem right to me. The covered answer is “10 more”

What is that starting with j sound? Please

i can’t exactly remember the rules but i’m thinking a - a doesn’t equal 5, but this is also technically 1 solution because you could solve for a, but i also don’t know how to solve for a variable with no number or if it’s even possible

Can I get some help setting up equation I have forgot what it is

Could someone tell me how negative nine, minus negative ten, doesn’t equal negative one? Any help at all would be greatly appreciated!!

Currently learning about the Pythagorean theorem

I am confused should I be using the triangle angle sum theorem orrr what please help me

Attempting to solve this with my son. I am not sure how to answer this one. We did 72/9=8 but we cannot figure out the shape.

2nd grade math question

I helped my son with homework and question #3 has me confused as to what the teacher was looking for here. I took the question as “choose all that apply” and interpreted the question simply as “choose every answer that adds up to six.”

The teacher only put a star next to “letter B” which I interpret that she’s saying is the only correct answer, not “letter A”, as well.

My wife and mother in law both agree with the teacher but I don’t get it.

My son and I both thought A and B were the correct answers. If A isn’t, why not?

Please help me understand so I don’t lead my kid astray.

Thank you!

Hello my brother failed a test because the teacher said he was multiplying the multiplication arrays incorrectly. I understand why that would be incorrect if the teacher said to write rows before columns in the instructions. But those instructions were not present and the grouping was not obvious. So, are all of these incorrect? I thought because multiplication was commutative and associative, these would be ok answers (except for number 2 though lol). Thank you for taking the time to read this!

∠A= 29°

∠B= 82°

∠C= 69°

The question is used to practice Law of Sines, but I’m not sure how I can find side b using the three angles? For all the other questions on this worksheet includes either 2 angles and 1 side or 2 sides and 1 angle, both of which I can do. This is the only question that didn’t have a given side.

She came home and asked me and I initially assumed the answer was 7, 4, 6, but then I was also confused by the last line. Can someone explain this to me?

Little brother's homework. Can't figure it out. Please help, i'm feeling dumb.

Could someone also help me out with 12th? I tried rationalising, but it didn't work and the solution includes using the difference of cubes but how? It's 1/3

3 seems to be correct, and I even downloaded some ai just to prove my answer, and every single ai agreed that the answer was 3.
