show your work

Answers

Answer 1
Answer: To get the answer you have to find the least common denominator of 7 and 6. the answer is 42. so you multiply  4/7 by 6/6 to get 24/42 then you multiply 5/6 by 7/7 to get 35/42. the last step is to subtract 24/42 from 35/42 to get your final answer 11/42

Mario claims that a rhombus is sometimes a square, but a square is always a rhombus. Is he correct? Explain your answer.

Answers

That is correct.This is because a square has all the elements a rhombus has.A rhombus has 4 equal sides,just like a square does.And,a rhombus can't always be a square becase a square also contains 4 equal angles,while a rhombus doesn't.
yes he is a square and a rhombus are exactly the same shape and figure they both have 4 sides and can sometimes have all equal sides :)

Stefanie bought a package of pencils for $1.75 and some erasers that cost $0.25 each. She paid a total of $4.25 for these items, before tax ​Exactly how many erasers did Stefanie buy?

Answers

Firstly, we’d have to find the total price paid for erasers by subtracting the overall price from the amount she paid in pencils.

$4.25 - $1.75 = $2.50

From there, we can use the amount per eraser to find out how many erasers she bought. Since she spent $2.50 in erasers, we can multiply to find our missing number.

$0.25 x 10 = $2.50

Therefore, Stefanie bought 10 erasers.

Hope this helps! :)
she bout 9
4.25-1.75=2.50
.25x9=2.50
