((4x+15)/(5x)) = 1/2
4x+15 = (5x)/2
8x+30=5x
3x+30=0
3x=-30
x=-10
Answer: x = 18.439
Step-by-step explanation:
x³-x = 340
x² = 340
x = √340 = 18.439
Answer:
30 degrees
Step-by-step explanation:
A linear pair of angles add upto 180
So, y+150=180
y=180-150
=30
Answer: The equation has one solution
Step-by-step explanation: First , open the brackets
7( 12 - 2x ) = 4 (3 - 3x )
84 - 14x = 12 - 12x
collect the like terms
84 - 12 = - 12x + 14x
72 = 2x
Therefore divide through by 2
x = 72/2
x = 36
Therefore, the equation has only one solution
