Use distrubutive property <em>a(b + c) = ab + ac</em>

6(5r - 4) - 2(r - 7s - 3)

= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)

= 30r - 24 - 2r + 14s + 6

= (30r - 2r) + 14s + (-24 + 6)

<h3>= 28r + 14s - 18</h3>

Find the scale factor that was used to create the dilaton below
Ne4ueva [31]

Let:

k\cdot IW=I^{\prime}W^{\prime}

Where:

k = scale factor

IW = 12

I'W'= 8

so, solving for k:

\begin{gathered} k=\frac{I^{\prime}W^{\prime}}{IW} \\ k=\frac{8}{12}=\frac{2}{3} \end{gathered}

How do you ungroup a 3 digit number? My nephew is working on his homework and I have no clue how to help him.
Talja [164]

In monetary terms, you're making change. If you need more ones, you trade one 10 for 10 ones.

When I was in school, many years ago, we used small superscript-type numbers to show this:

  7 3 0 ⇒ 7 2 ¹0 . . . . regrouping to gain 10 ones

  7 2 ¹0 ⇒ 6 ¹2 ¹0 . . .regrouping again to gain 10 more tens

You'd have to look at the example problems that precede this page in order to see what the meaning of "magnifying glass" is.
