Would some one look at these problems and see if I got them right Thanks Just let me if they are wrong so I can go back over them
1.Write in simplest form 48/56
A. 6/7
2.Multiply 8x^3/5 *10/x^3
A. 16/x^4
3.Divide 4/x^7 / 12/x^3
A. 1/3x^2
4. divide x^2-36y^2/5x^2+30y / (x^26xy)
A. (x+6y)/(5x)(x^2+6y)
5.Subtract. Express your answer in simpliest form
3x/14-x/14
A. x/7
6.Add. Express your answer in simplest form. x^2/x+1 + 5x+4/x+1
A. x+4
7.Add. Express your answer in simplest form.
2x/x^2+15x+54 + 4/x+6
A. 6/x+9
8.Solve. x/7 - 1/2 = x-11/2
A. x=14
9.solve 9/x-5 -1= 8/x+5
A. x= -10 and 11
10.Solve 2/3 = 12/x
A. x=18
11. Simplify 6/8 over 2/18
A.39/4
1.Write in simplest form 48/56
A. 6/7
OK
2.Multiply 8x^3/5 *10/x^3
A. 16/x^4
NO
3.Divide 4/x^7 / 12/x^3
A. 1/3x^2
NO
4. divide x^2-36y^2/5x^2+30y / (x^26xy)
A. (x+6y)/(5x)(x^2+6y)
I can't tell what the problem is.
5.Subtract. Express your answer in simpliest form
3x/14-x/14
A. x/7
OK
6.Add. Express your answer in simplest form. x^2/x+1 + 5x+4/x+1
A. x+4
OK
7.Add. Express your answer in simplest form.
2x/x^2+15x+54 + 4/x+6
A. 6/x+9
I don't know what the problem is.
8.Solve. x/7 - 1/2 = x-11/2
A. x=14
OK if the problem is
(x/7)-1/2 = (x-11)/2
9.solve 9/x-5 -1= 8/x+5
A. x= -10 and 11
I don't know the problem.
10.Solve 2/3 = 12/x
A. x=18
OK
11. Simplify 6/8 over 2/18
A.39/4
NO
Check my arithmetic.
