If u want to switch one side doing multiplying to the other side, u have to change it to division
9n = 5
n = 5/9
n = 0.56 ( rounded to 2 dp)

Montano1993 [528]

Answer:

$\large \boxed{12}$

Step-by-step explanation:

We can apply Pythagoras' Theorem.

$\begin{array}{rcc}a^{2} & = & b^{2} + c^{2}\\13^{2}& = & 5^{2} + c^{2}\\169& = & 25 + c^{2}\\c^{2}& = & 144\\c & = & \sqrt{144}\\& = & \mathbf{12}\\\end{array}\\\text{The other leg of the triangle is $\large \boxed{\mathbf{12}}$}$

What is x and the measurements?

nikitadnepr [17]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the sum of the measures of the 3 sides.

Sum the sides and equate to 75, that is

2x - 9 + 3x + 4 + 2x + 3 = 75, that is

7x - 2 = 75 ( add 2 to both sides )

7x = 77 ( divide both sides by 7 )

x = 11

Thus

AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m

BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m

AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m

Parenthesis:

3 * 2 = 12

12 - 12 = 0

12 - 0 = 12

10^2 * 12

10 ^ 2 = 144

144 * 12 = 1728

1728 + 15 = 1743

1743 + 6 = 10458

How to solve<br> -22-x=5+6x+9

nadya68 [22]

-22 - x = 5 + 6x + 9 Combine like terms (5 and 9)
-22 - x = 14 + 6x Subtract 6x from both sides
-22 - 7x = 14 Add 22 to both sides
-7x = 36 Divide both sides by -7
x = 5 $\frac{1}{7}$
