Answer:
56
Step-by-step explanation:
If you would like to solve the inequality x - 5/x < 4, you can do this using the following steps:
<span>x - 5/x < 4
</span>x^2 - 5 < 4x
x^2 - 4x - 5 < 0
(x - 5) * (x + 1) < 0
x < 0
1. x = 5
2. x = -1
The correct result would be x = -1.
Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
Answer : 12312
Step-by-step explanation : According to BODMAS, Addition (+) comes first
