Question

Drag and drop numbers into the boxes so that the paired values are in a proportional relationship.

x 2 4 [A] 7 9
y 1 2 3 3.5 [B]

Options: 3 / 3.5 / 4.5 / 5 / 6

Answer Examlpe:

A= 6 and B= 3.5

Answer 1

Answer:

A=6 and B=4.5

Step-by-step explanation:

You are given table

$\begin{array}{cccccc}x&2&4&[A]&7&9\\y&1&2&3&3.5&[B]\end{array}$

If the paired values are in a proportional relationship, then

$\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{[A]}{3}=\dfrac{7}{3.5}=\dfrac{9}{[B]}.$

Note that

$\dfrac{2}{1}=\dfrac{4}{2}=\dfrac{7}{3.5}=2,$

then

$\dfrac{[A]}{3}=2\Rightarrow [A]=6,\\ \\\dfrac{9}{[B]}=2\Rightarrow [B]=\dfrac{9}{2}=4.5.$
