X+6/2 + 5−4x/3 − 8−x/6 =0

natka813 [3]

Answer:

x = 0

Step-by-step explanation:

x+\frac{6}{2}+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-4\cdot \frac{x}{3}-8-\frac{x}{6}=0

x+3+5-\frac{4x}{3}-8-\frac{x}{6}=0

x-\frac{4x}{3}-\frac{x}{6}+3+5-8=0

x-\frac{4x}{3}-\frac{x}{6}=0

x\cdot \:6-\frac{4x}{3}\cdot \:6-\frac{x}{6}\cdot \:6=0\cdot \:6

6x-8x-x=0

-3x=0

\frac{-3x}{-3}=\frac{0}{-3}

Solve for n 50 points <br><br> a=p(1+r/n)^rn

Andreyy89

Answer:

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

Step-by-step explanation:

$a=p(1+\frac{r}{n} )^{nt}$

$\frac{a}{p} =(1+\frac{r}{n} )^{nt}$

$\sqrt[nt]{\frac{a}{p}} =(1+\frac{r}{n} )$

$\sqrt[nt]{\frac{a}{p}} -1 =(\frac{r}{n} )$

$n = \frac{r}{\sqrt[nt]{\frac{a}{p}} -1 }$

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]

3.9x + 1.4 = 17 what is the steps

Vedmedyk [2.9K]

Answer:

$x=4$

Step-by-step explanation:

$3.9x + 1.4 = 17$

Having a decimal is not very nice to deal with, so we multiply all sides by 10 to get rid of the decimals.

$3.9x*10+1.4*10=17*10$

$39x+14=170$

Subtract 14 from both sides:

$39x+14-14=170-14$

$39x=156$

Divide both sides by 39:

$\frac{39x}{39}=\frac{156}{39}$

$x=4$
