3 0

Answer:

b=5

Step-by-step explanation:

-b - 19 = -3b – 9

Add 3b to each side

-b+3b - 19 = -3b+3b – 9

2b -19 = -9

Add 19 to each side

2b-19+19 = -9+19

2b = 10

Divide by 2

2b/2 =10/2

b=5

Amount in compound interest = p(1 + r)^n where p is the initial deposit, r = rate and n = period.
Here, Amount after 36 months = 1000(1 + 0.1/100)^36 = 1000(1 + 0.001)^36 = 1000(1.001)^36 = 1000(1.036637) = $1,036.64

15m+9n=-6 solve for n
Yanka [14]

Answer:

( - 2 - 5m ) / 3

Step-by-step explanation:

15m + 9n = - 6

9n = - 6 - 15m

Divide by 3 on both sides,

9n / 3 = - 6 / 3 - 15m / 3

3n = - 2 - 5m

n = ( - 2 - 5m ) / 3

If each interior angle of a regular polygon is 162 how many sides does it have
Yuri [45]

Answer:

20 sides

Step-by-step explanation:

The formula that relates interior angles with number of sides is:

Each \ Interior = \frac{(n-2)*180}{n}

Where

n is the number of sides.

We know each interior is 162 degrees, so we substitute and cross multiply and solve for n:

Each \ Interior = \frac{(n-2)*180}{n}\\162=\frac{(n-2)180}{n}\\162n=(n-2)180\\162n=180n-360\\18n=360\\n=20

THus, the polygon has 20 sides
