Answer:

1.82n

Step-by-step explanation:

We combine like terms to simplify this.

Any variable with no other coefficient can be written with a coefficient of 1. This is because everything can be multiplied by 1 without changing it. This means we have

1n + 1n - 0.18n

Combining like terms, we have

2n - 0.18n = 1.82n

What is the solution of 3+ x-2/x-3 less than or equal to 0

bagirrra123 [75]

Answer:

The solution set consists of all the real numbers smaller than or equal to 11/4:

$x\leq \frac{11}{4}$

Step-by-step explanation:

We need to solve for x (that means isolate x on one side of the inequality symbol) in the following inequality:

$3+\frac{x-2}{x-3} \leq 0\\\frac{x-2}{x-3} \leq -3\\x-2\leq -3\,(x-3)\\x-2\leq -3x+9\\x+3x\leq 9+2\\4x\leq 11\\x\leq \frac{11}{4}$
