Six times the sum of a number and four is -12. Find the number and show work.
Alina [70]

Answer:

<em>The number is -6.</em>

Step-by-step explanation:

Let x = the unknown number

"the sum of a number and four" = n + 4

"Six times the sum of a number and four" = 6(n + 4)

"Six times the sum of a number and four is -12." is the equation

6(n + 4) = -12

Divide both sides by 6.

n + 4 = -2

Subtract 4 from both sides.

n = -6

What is the length of the intercepted arc?
raketka [301]

First you need to calculate the circumference of the circle:

Circumference = diameter x PI =  16 x PI = 16 * 3.14 = 50.24

The intercepted arc is 15 degrees.

To find the length multiply the circumference by the central angle divided by 360.

Arc length = 50.25 x (15/360) = 2.1 units.
