X:y = 9:7 Form an equation that links x and y

sleet_krkn [62]

Equations are expressions with equal values

The equation that links x and y is $7x = 9y$

<h3>How to determine the equation</h3>

The ratio is given as:

$x : y = 9 : 7$

Express the ratio, as a fraction

$\frac xy = \frac 97$

Cross multiply

$7 *x = 9 * y$

Evaluate the product

$7x = 9y$

Hence, the equation that links x and y is $7x = 9y$

Using Eulers formula, how many edges does a polyhedron with 9 faces and 14 vertices have?

qwelly [4]

<h3>By Euler's Formula </h3>

F + V = E + 2

<h2><u>Solution</u></h2>

F = 9

V = 14

E = ?

<h3>Substuting the values</h3>

⇨ 9 + 14 = E + 2

⇨ 23 = E + 2

⇨ 23 - 2 = E

⇨ 21 = E

Hence , the number of edges in polyhedron is 21.
