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

Hellllllllllllllllllllllllllllp!!!!!!!!!!!!!!!! will give brainliest
zavuch27 [327]

Answer:

Step-by-step explanation:

3in/4 = 0.75in(Diameter) for each circle

r = 0.375

A = πr^2

A(for 1 circle) = 0.141π

A(for 1/4 circle) = 0.035π

A x 4 because we have 4 circles =

0.141π

0.141π(area of middle) + 0.141π(area of circle) =

0.282π or 0.886in^2
