In order to solve the formula

in terms of d, you simply have to divide both sides by pi:

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

So, the total height is

Answer:
2534.081
Step-by-step explanation:
Answer:
1. No solution
2. Infinite solutions
Step-by-step explanation:
1. To solve the system, set the equations equal to each other and solve for x.
2x - 5 = 2x + 7
-5 = 7
This is a false statement. This means there is no solution.
2. To solve the system, graph each equation.
y = -3/4 x - 5/2 has a y-intercept -5/2 and slope -3/4.
3x + 4y = -10 converts to y = -3/4x -5/2.
This graphs as the exact same line. This system has infinite solutions.
15 x 100= 1500 centimeters
375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased
Step-by-step explanation:
Let x be the number lower reserved tickets
and
y be the number of upper reserved tickets
Then according to given statements

From equation 1:

Putting in equation 2

Subtracting 7030 from both sides

Dividing both sides by -1.5

Putting y = 365 in equation 1

Hence,
375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased
