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

Solve for b<br> 2(-2b+3)=9

Alexxx [7]

Answer:

b=-3/4 or b=-0.75

Step-by-step explanation:

$2(-2b+3)=9$

$2b+3=\cfrac{9}{2}$

$-2b=\cfrac{9}{3} -3$

$-2b=\cfrac{3}{2}$

$b=-\cfrac{\frac{3}{2} }{2}$

$b=-\cfrac{3}{2\times 2}$

$b=-\cfrac{3}{4}$

What is the converse of r->(~q v p)

alexira [117]

Answer:

$r => (\neg q \ \lor p) \ \equiv \ q \ \land \ \neg p => \neg r$

Step-by-step explanation:

In general, remember that the converse of $a => b$ is $\neg b => \neg a$ , therefore in this case $a = r \ \ , b = \neg q \ \lor p$

so $r => (\neg q \ \lor p) \ \equiv \ q \ \land \ \neg p => \neg r$
