Mathematics
1 answer:
Sauron [17]3 years ago
7 0

Answer:

Step-by-step explanation:

17)-8(5-n)=-96

 -8*(5-n)-(-96)=0

 (0 -  8 • (5 - n)) -  -96  = 0

 8n + 56  =   8 • (n + 7)

 8 • (n + 7)  = 0

Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    n+7 = 0  

Subtract  7  from both sides of the equation :  

                     n = -7

n = -7 is your answer

Answer: There are <u>4</u> teams in the league

Step-by-step explanation:

(1) Add 14 four times: 14+14+14+14 = 56

(2) Multiply 14 four times: 14 x 4 = 56

(3) Combine both of these numbers into the <em>t  </em>factor: 14t = 56

(4) Divide both sides by 14 and simplify: (14t / 14) = 56/14 | t = <u>4</u> (simplified)

The volume of a cone is 62.8 cubic inches. The height of the cone is 15 inches. What is the radius of the cone, rounded to the n
Setler79 [48]
R = sqrt 3 * (V /( pi * h))
V = 62.8
pi = 3.14
h = 15
now we sub
R = sqrt 3 * (62.8 / (3.14 * 15)
R = sqrt 3 * (62.6 / 47.1)
R = sqrt 3 * 1.33
R = sqrt 3.99
R = 1.9 rounds to 2 inches <===
