How do I do this please help
Umnica [9.8K]

Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ \frac{2}{3}

=3 \times \frac{3}{2}

=\frac{3 \times 3}{2}

=\frac{9}{2}

but andre calculated it as

=4\tfrac{1}{3}

=\frac{4 \times 3 + 1}{3}

=\frac{13}{3}

Hence his calculation was incorrect at initial level itself

Explain why 2a+3b=5ab
Ahat [919]

That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.

If you had 2a+3a, then it would simplify to 5a

Similarly, 2b+3b = 5b

Or you could have 2ab+3ab = 5ab

The key is that the variable portions must match up to be able to add them.

Combine the like terms to create an equivalent expression<br> -k - ( - 8k)
Svetllana [295]

____________________________________________________

Answer:

7k

____________________________________________________

Step-by-step explanation:

We are trying to combine like terms with the expression: -k - ( - 8k)

We are pretty much solving it.

Solve:

-k - ( - 8k)

The "- ( -" turns into a plus sign.

So it would look like:

-k - -8k or -k + 8k

Now, you would finish solving

-k + 8k = 7k
