Answer 1

Do you have any ideas? What would you think to do first? :)

Answer 2

multiply 6x4 then multiply the proudut to13

Answer 3

Sounds good! Let's try that and see what happens.

Answer 4

Looks like I'm getting 312 after doing that. How about you?

Answer 5

yeps

Answer 6

Great, so I guess we are at
312 = k x 13

Answer 7

Now what would you do?

Answer 8

Step 1: Simplify both sides:\[6 × 4 × 13 = k × 13 = 312=13 \times k\]

Answer 9

all i need to know is the value k

Answer 10

Step 2: Flip the Equation:\[312=13\times k~becomes~13\times k=312\]

Answer 11

Right! So, we know what 13 times k is, how could you find k by itself? :)

Answer 12

:D

Answer 13

Step 3: Divide both sides by 13:\[\frac{ 13\times k }{ 13 } = \frac{ 312 }{ 13 }\]

Answer 14

\[k = 24\]

Answer 15

Hey, look! There's a great idea right there. :) Just divide both sides by 13. This leaves us with k.
