Answer:

10x+30 +16x +24 +2 = 26x +57

10x + 16 x + 30 + 24 +2 = 26x + 57

26x + 56 = 26x +57

56 = 57

Answer:

$x=\sqrt6\\y=\sqrt{12}$

Step-by-step explanation:

We know that since angles in a triangle add up to 180º, the remaining angle must be 45º.

So the side with length $x$ must be equal to the side with length $\sqrt6$ . That is:

$x=\sqrt6$

Now, by Pythagoras:

$y=\sqrt{(\sqrt6)^2+(\sqrt6)^2}\\=\sqrt{6+6}\\=\sqrt{12}$

Solve the system: 2/x - 3/y =-5; 4/x + 6\y =14

sertanlavr [38]

The solution is $x = 2 \text{ and } y = \frac{1}{2}$

Solution:

Let us assume,

$a = \frac{1}{x}\\\\b = \frac{1}{y}$

Given system of equations are:

$\frac{2}{x} - \frac{3}{y} = -5$

$\frac{4}{x} + \frac{6}{y} = 14$

Rewrite the equation using "a" and "b"

2a - 3b = -5 ------------ eqn 1

4a + 6b = 14 -------------- eqn 2

Let us solve eqn 1 and eqn 2

Multiply eqn 1 by 2

2(2a - 3b = -5)

4a - 6b = -10 ------------- eqn 3

Add eqn 2 and eqn 3

4a + 6b = 14

4a - 6b = -10

( - ) --------------------

8a = 4

$a = \frac{4}{8}\\\\a = \frac{1}{2}$

Substitute a = 1/2 in eqn 1

$2(\frac{1}{2}) -3b = -5\\\\1 - 3b = -5\\\\3b = 6\\\\b = 2$

Now let us go back to our assumed values

Substitute a = 1/2 in assumed values

$a = \frac{1}{x}\\\\\frac{1}{2} = \frac{1}{x}\\\\x = 2$

Substitute b = 2 in assumed value

$b = \frac{1}{y}\\\\2 = \frac{1}{y}\\\\y = \frac{1}{2}$

Thus the solution is $x = 2 \text{ and } y = \frac{1}{2}$

What is 17 37/50 turned into a decimal

FromTheMoon [43]

Because 17 37/50 is a mixed fraction, we must convert it into an improper fraction:

$17 \frac{37}{50}$
$17 * 50 = 850$
$850 + 37 = 887$
$\frac{887}{50}$

To make dividing the fraction easier, we can multiply the numerator and denominator by 2:

$\frac{887}{50} * \frac{2}{2} = \frac{1774}{100}$

Now it's easier to divide the numerator by the denominator:

$1774 \div 100 = 17.74$

17 37/50 converted into a decimal is 17.74.
