Question

1. simplify by removing the parenthses and collecting like terms. 83q - (39q-38)=44q+38?

2. solve for y---z=ym answer y=z/m?

3. divide if possible -6/"over" 17 divided by (-5/"over"17)=undefined?

4. translate to algerbirc expression the sum of c and n= c+n?

5.one day the tempature dropped from 6 degrees ferheit to -17 degrees ferhiet how many degrees did it drop? 23 degrees?

6. true statement 1 > -6

7. simplify [15 divided by(-3)]divided by (-1/"over"4)=48?

8. find decimal notation for 14/25=0.56?

9. translate into algerbraic expression four more than twice a number= 2x+4?

10. solve 7(x+4)=9(x-2)=x=23?

11. subtract -5/"over"26- (-3/"over"13)= -11/26?

12. subtract -8-5=-13?

13. solve using principles together 7x-7= 13+12x= x=4?

Answer 1

7. does not look right. Dividing by -1/4 is the same as multiplying by -4.

10. Too many = signs in what you wrote.
7x + 28 = 9x - 18
2x = 46
x = 23 should be written separately

11. Two minuses make a plus, but that is not what you did

13. There are too many = signs again.

Answer 2

on 11 i was trying to write them as fraction i was afriad you would not be able to read them so it reads subtract -5/26-(-3/13)= -11/26?

on 13. the problem is solve using principles together 7x-7=13+12x

my answer is x=4?
would that be right?



7. simplify [15/(-3)]/ (-1/"over"4)=8?

Answer 3

12. is -13? i was not sure if you could see the negative sign...thank u so much!

Answer 4

7. is still wrong
11. is still wrong
You don't need to write "over".
13. is correct

Answer 5

algebra is also spelled incorrectly

Answer 6

11. subtract -5/"over"26- (-3/"over"13)= -8/39?

7. simplify [15 divided by(-3)]divided by (-1/"over"4)=1.25?

Answer 7

Get rid of the "over". One doesn't write algebraic expressioons that way.

-5/26 -(-3/13) = -5/26 + 6/26 = 1/26

Answer 8

were these right?

7. simplify [15/(-3)]/ (-1/4)=1.25?

12. is -13? i was not sure if you could see the negative sign...thank u so much!
