## lvasquev462 Group Title translate into algebraic expression the product of three and a number increased by five one year ago one year ago

1. yakeyglee

Let $$n$$ represent our number. How would we write three times that number ($$3 \times$$)? How would we write that increased by five ($$+5$$)?

2. e.cociuba

x=3+x*5

3. e.cociuba

x equals three, plus x, times 5

4. yakeyglee

@e.cociuba, that's not quite correct. You should have an expression, not an equation.

5. amistre64

the lack of commas makes this a bit ambiguous to me

6. lvasquev462

so it will be n=3+x

7. e.cociuba

k so then u help us all out here. im a bit confussed!

8. amistre64

no

9. amistre64

i see 2 ways of interpreting this .... which makes it ambiguous to me the product of: (three and a number) increased by five the product of: three and (a number increased by five)

10. amistre64

the first option is my gut instinct tho

11. lvasquev462

ok

12. amistre64

how would you write the product of three and a number?

13. lvasquev462

times 3

14. amistre64

yes; but lets use 3*x just to be safe :) then just add five to it

15. lvasquev462

3*x+5

16. amistre64

good

17. e.cociuba

thats the same thing i did, i just did 3+x*5 (u just switched the 3 and 5)

18. e.cociuba

rite?

19. amistre64

your math sentence does not reflect the english wording.

20. lvasquev462

can u help me with an another

21. lvasquev462

fifteen less than twice a number

22. amistre64

yours represents: what is the sum of 3, and the product of 5 and a number

23. amistre64

how would you write: twice a number

24. e.cociuba

Oh well I’m sorry for confusing u guys with my English wording.

25. lvasquev462

i am not sure

26. amistre64

twice also can be read as "2 times" so (2 times a number) can be written as?

27. lvasquev462

n*2

28. amistre64

good; and when we less that by fifteen .... which means we subtract 15 from it we get?

29. lvasquev462

n*2-15

30. amistre64

correct. or another way that you can write it is: 2*x - 15

31. amistre64

good luck ;)
