To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.

Multiply normally, ignoring the decimal points.
Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.

What is the solution of the system?

Dmitry_Shevchenko [17]

We have $\begin{bmatrix}2x+y=20\\ 6x-5y=12\end{bmatrix}$

$\mathrm{Multiply\:}2x+y=20\mathrm{\:by\:}3:\ 6x+3y=60$

$\begin{bmatrix}6x+3y=60\\ 6x-5y=12\end{bmatrix}$

6x - 5y = 12
-
6x + 3y = 60
/
-8y = -48

$-8y=-48 \ \textgreater \ \mathrm{Divide\:both\:sides\:by\:}-8 \ \textgreater \ \frac{-8y}{-8}=\frac{-48}{-8} \ \textgreater \ y=6$

$\mathrm{For\:}6x+3y=60\mathrm{\:plug\:in\:}\ \:y=6$

$6x+3\cdot \:6=60 \ \textgreater \ \mathrm{Multiply\:the\:numbers:}\:3\cdot \:6=18 \ \textgreater \ 6x+18=60$

$\mathrm{Subtract\:}18\mathrm{\:from\:both\:sides} \ \textgreater \ 6x+18-18=60-18 \ \textgreater \ 6x=42$

$\mathrm{Divide\:both\:sides\:by\:}6 \ \textgreater \ \frac{6x}{6}=\frac{42}{6} \ \textgreater \ x = 7$

Therefore....
$The\:solutions\:to\:the\:system\:of\:equationts\:are \ \textgreater \ y=6,\:x=7$

Answer:

$\frac{\sqrt{6} }{4}$ , 1.538..., $\frac{19}{7}$ , $\sqrt{29}$

Step-by-step explanation:

Solve them each on the calculator and then put in order

$\frac{\sqrt{6} }{4}$ = 0.6123...

19/7 = 2.714

$\sqrt{29}$ = 5.385...

Solve for X-4 1/6 = 9 1/3

Gala2k [10]

Answer:

13 1/2

Step-by-step explanation:

X-4 1/6 = 9 1/3

Add 4 1/6 to each side

X-4 1/6+ 4 1/6 = 9 1/3 + 4 1/6

x = 9 1/3 + 4 1/6

= 9 2/6 + 4 1/6

13 3/6

13 1/2
