6. phi

can you do this part 15.5 + (-24) ?

7. phi

I would do "normal subtraction" 24 - 15.5 and then make the answer negative

8. anonymous

-8.5

9. phi

ok so (2/3) * (15.5 + (-24) ) + (-18) becomes (2/3) * -8.5 -18 order of operations: do multiply first what is 2*-8.5 ?

10. anonymous

no its 2/3 the fraction

11. phi

yes. but 2/3 means (or at least you can interpret it as) multiply by 2, then divide by 3 btw, after we are done , none of the choices match the number we get. Are you sure there is no typo?

12. anonymous

no thoes are th choices to choose from

13. anonymous

@phi its -17

14. phi

(2 * -8.5)/3 = -17/3 now we have (2/3) * (15.5 + (-24) ) + (-18) (2/3) * -8.5 - 18 -17/3 - 18 we can change 18 to 3*18/3 so the problem is $- \frac{17}{3} - \frac{54}{3}$

15. anonymous

im not good with fractions i suck at them

16. phi

that becomes $- \frac{71}{3} = -23 \frac{2}{3}$

17. anonymous

ok

18. phi

can you post a screen shot of the original question? Something is wrong.
