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?

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.

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?

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

7. is still wrong
11. is still wrong
You don't need to write "over".
13. is correct
11. is still wrong
You don't need to write "over".
13. is correct
drwls
algebra is also spelled incorrectly

11. subtract -5/"over"26- (-3/"over"13)= -8/39?
7. simplify [15 divided by(-3)]divided by (-1/"over"4)=1.25?
7. simplify [15 divided by(-3)]divided by (-1/"over"4)=1.25?
drwls
Get rid of the "over". One doesn't write algebraic expressioons that way.
-5/26 -(-3/13) = -5/26 + 6/26 = 1/26
-5/26 -(-3/13) = -5/26 + 6/26 = 1/26
Nashea
were these right?
7. simplify [15/(-3)]/ (-1/4)=1.25?
