Its simple what you do is you subtract not divide because if you where dividing you would be putting something into groups equally and not Addison because your not trying to find how much in all so it would be Subtraction another way is to see if there is how many more or How much more so if you see that then you know that its Subtraction! Hope this helps!:)
Answer: False
Step-by-step explanation: right triangles need two equal angles and one different.
14. 5n - 4 = 8
5n = 12
n = 2.4
15. 3x + 5 - 4x = -3
-x + 5 = -3
-x = -8
x = 8
16. 96 = -6(-4 - 3y)
96 = 24 + 18y
72 = 18y
4 = y
17. 3(x - 5) = -14 + 17x
3x - 15 = -14 + 17x
-11x - 15 = -14
-11x = 1
x = -0.0909
18. 7z + 10 - z = 8z - 2(z - 5)
6z + 10 = 8z - 2z + 10
6z + 10 = 6z + 10
6z = 6z
z = z (all real numbers are solutions)
Hope this helps.
