Solve for n: 7(n - 6) = a(n + 5)

Morgarella [4.7K]

Answer:

n = $\frac{(5a + 42)}{( 7 - a ) }$

Step-by-step explanation:

7(n - 6) = a(n + 5)

7n - 42 = an + 5a

7n - an = 5a + 42

n( 7 - a ) = 5a + 42

n = $\frac{(5a + 42)}{( 7 - a ) }$

Find the perimeter of this semi-circle with diameter,

yan [13]

Answer:

The answer to your question is P = 17(π + 2) or 17π + 34

Step-by-step explanation:

Data

Diameter = 34 cm

Formula

P = rπ + 2r

Process

1.- Find the radius

radius = diameter / 2

radius = 34 / 2

radius = 17 cm

2.- Substitute the values in the formula

P = 17π + 2(17)

3.- Simplification

P = 17π + 34

4.- Factor

P = 17(π + 2)
