Use the distributive property to simplify the expression below: -5x + 20 Divided by -5

19. minnie123

same like the one above -5 divided by -5 is 1 or x... -5 divided by 20 is -4 so x-4 should be the answer

20. jlongSwag27

thanks

21. minnie123

22. jlongSwag27

It asks me to Simplify the following expression. 2x − 2y + 3z − 2x − y + 2z = ? A) 4x − 3y + 5z B) −2y − 3y + 5z C) −2x − 3y + 6z D)−3y + 5z How would i do this??

23. sarahashley

24. jlongSwag27

Okay but i just wanna know how i would find A to be the correct answer. What are the steps , the like terms??

25. sarahashley

cz u do the like terms cz 2x times 2x is 4 and so on>>>

26. minnie123

damn where you come from like let a chick have a chance @sarahashley .... but i guess thats right what she said all the like terms or all the ones that have the same letter behind them you combine

27. sarahashley

2x times 2x is 4x and 2y minus y is -3y and then 3z plus 2z is 5z

28. jlongSwag27

Haha :) thank you both so much i am loving all the help, im good a t math but sometimes i suck.

29. sarahashley

yeah

30. minnie123

Use the distributive property to simplify the expression below: t − 5(3 + t) A) −4t + 15 B) −5t − 2 C) −5t − 15 D) −4t − 15

32. zordoloom

It would be d. Just multiply 3 by 5 and 5 by 5. Dont forget the negative

33. zordoloom

*5 by t

34. sarahashley

its a -4t+15

35. jlongSwag27
