Answer:

0 = 0

Step-by-step explanation:

2+5x−7=3x−9+2x

Step 1: Simplify both sides of the equation.

−2+5x−7=3x−9+2x

−2+5x+−7=3x+−9+2x

(5x)+(−2+−7)=(3x+2x)+(−9)(Combine Like Terms)

5x+−9=5x+−9

5x−9=5x−9

Step 2: Subtract 5x from both sides.

5x−9−5x=5x−9−5x

−9=−9

Step 3: Add 9 to both sides.

−9+9=−9+9

0=0

Solve for x: 4 over x equals 5 over 10

julsineya [31]

Answer:

x = 8,

Step-by-step explanation:

$\displaystyle \frac{4}{x} = \frac{5}{10}$ .

$x \ne 0$ for it is a denominator. Multiply both sides with the product of the two denominators: $10\;x$ :

$\displaystyle \frac{4}{x}\cdot (10\; x) = \frac{5}{10}\cdot (10\;x)$ .

$40 = 5\; x$ .

Multiply both sides by one over the coefficient of x:

$\displaystyle \frac{1}{5} \times 40 = \frac{1}{5}\times 5\; x$ .

$x = 8$ .

Work out length of BC

Neporo4naja [7]

Answer:

assume $13 = z \\ 8 =x \\ bc = y$

by phytagorean theorem

${y}^{2} + {x}^{2} = z^{2}$

$bc = y = \sqrt{ {z}^{2} - {x}^{2} } = \sqrt{169 - 64} = \sqrt{105}$
