dalvyx [7]3 years ago
5 0

Answer:

Answer below!

Step-by-step explanation:

15x^{2} -25x=0\\5x(3x-5)=0\\                           \frac{5x}{5}=\frac{0}{5} ;x=0

3x - 5 = 0

Add 5 to both sides;

3x = 5

Divide both sides by 3;

x=\frac{5}{3}

Solve the following inequality: –1 6(–1 – 3x) > –39 – 2x
jeka57 [31]
If you would like to solve the inequality <span>–1 + 6 * (–1 – 3x) > –39 – 2x, you can do this using the following steps:

</span>–1 + 6 * (–1 – 3x) > –39 – 2x
-1 - 6 - 18x > -39 - 2x
-7 + 39 > -2x + 18x
32 > 16x
32/16 > x
x < 2

The correct result would be x < 2.
