$z+(-0.72)=-2.5\\\\\text{Step 1}:\ x+(-0.72)+(-0.72)=-2.5+(-0.72)\qquad\text{ERROR}\\\\CORRECT\ IS:\ x+(-0.72)-(-0.72)=-2.5-(-0.72)\\\\\text{Step 2}:\ x=-2.5+0.72\\\\\text{Step 3}:\ x=-1.78$

Subtract, not add, -0.72 from both sides.

6y − 1.5x = 8 please help

Furkat [3]

6y-1.5x=8
multiply both sides of the equation by 10
60y-15x=80
divide both sides
12y-3x=16
use the commutative property to reorder the terms
-3x+12y=16
change the signs on both sides of the equation
your answer will be : 3x-2y=-16

Multiply the rational expressions: Divide the rational expressions:

Montano1993 [528]

Answer:

1). $\frac{2}{(x+1)}$

2). $\frac{x^2}{2(x+1)}$

Step-by-step explanation:

For multiplication of the rational expressions,

$\frac{x}{(x+1)}\times \frac{2}{x}$

= $\frac{2x}{x(x+1)}$

= $\frac{2}{(x+1)}$

For division of the rational expressions,

$\frac{x}{(x+1)}\div \frac{2}{x}$

= $\frac{x}{(x+1)}\times \frac{x}{2}$

= $\frac{x^2}{2(x+1)}$

[When the divisor is a rational expression or a rational number, we change the sign from division to multiplication and reciprocate or flip the fraction.

This is applicable for division of the rational expressions only].

Write the fractional equivalent (in reduced form) to each number.

LenaWriter [7]

Here you go:

1) 0.3 = 3/10
2) 0.125 = 1/8
3) 0.16 = 16/100 = 8/50 = 4/25
4) 0.1 = 1/10
5) 0.6 = 6/10 = 3/5
6) 0.2 = 2/10 = 1/5
7) 0.75 = 75/100 = 3/4
