## anonymous one year ago What is the value of the expression? https://static.k12.com/bank_packages/files/media/mathml_6d85625add616571d12ddc5ede49a2257775e240_1.gif

the "dot" should mean "times" :) (unless it's a decimal LOL) So we want to solve the following: $\frac{ 9 \times 3 - 3 \times 5 }{ 4} = ?$

2. butterflydreamer

Firstly, work out what 9 times 3 equals to ? and then, 3 times 5 equals to ?

not quite.

5. anonymous

well 9x3 is 27 and 3x5 is15

6. butterflydreamer

corrrect! So if we plug that into our equation we have this: $\frac{ 9 \times 3 - 3 \times 5 }{ 4 }$ $= \frac{ 27 - 15 }{ 4 }$ Now, we want to simplify this. What does 27 - 15 = ?

7. anonymous

12!

8. butterflydreamer

excellent! :D So now we have $\frac{ 12 }{ 4 } = ?$ 12 divided by 4 equals to?

9. anonymous

3

10. butterflydreamer

correect! :D Good job

11. anonymous

thanks!

12. butterflydreamer

no problem (:

13. anonymous

What is the value of the expression? (5 + 10) ÷ 5

14. anonymous

that would be 3?
