## anonymous one year ago What is the value of k? 6 × 4 × 13 = k × 13 A. 10 B. 24 C. 52 D. 78

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

2. anonymous

multiply 6x4 then multiply the proudut to13

3. jtvatsim

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

4. jtvatsim

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

yeps

6. jtvatsim

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

7. jtvatsim

Now what would you do?

8. KendrickLamar2014

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

9. anonymous

all i need to know is the value k

10. KendrickLamar2014

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

11. jtvatsim

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

:D

13. KendrickLamar2014

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

14. KendrickLamar2014

$k = 24$

15. jtvatsim

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

COOLZ

17. jtvatsim

lol Not too bad. Good job!

18. anonymous

THANKS all i need is a push

19. jtvatsim

Yep, from what you started saying in the beginning, it seems like you have the basic ideas in place. With some more practice, you'll be all set.
