Answer:

<h3>- Add 9.6 to both sides of the equation </h3><h3>- Divide both side by the coefficient of x i.e 3.2</h3><h3></h3>

Step-by-step explanation:

The first step that can be done to both of the equation given is to add 9.6 to both sides of the equation as shown;

3.2x – 9.6 = 38.4

3.2x – 9.6+9.6 = 38.4+9.6

3.2x  = 38.4+9.6

3.2x = 48.0

step 2;

Divide both side by the coefficient of x i.e 3.2

3.2x/3.2 = 48.0/3.2

x = 15

Therefore the value of x is 15

A stadium has 52,000 seats. Seats sell for $42 in section A, $36 in section B, and $30 in section C. The number of seats in sect
Charra [1.4K]
Let the number of seats in section A be x, that of section B y and that of secyion C z. Then
x + y + z = 52000 . . . (1)
x = y + z . . . (2)
42x + 36y + 30z = 1960200 . . . (3)

Putting (2) into (1), gives
2x = 52000
x = 52000/2 = 26000
From (2) and (3), we have
y + z = 26000 . . . (4)
42(26000) + 36y + 30z = 1960200
36y + 30z = 1960200 - 1092000
36y + 30z = 868200 . . . (5)

(4) * 30 => 30y + 30z = 780000 . . . (6)

(5) - (6) => 6y = 88200
y = 88200/6 = 14700

From (4), z = 26000 - 14700 = 11300

Therefore, there are 26,000 seats in section A, 14,700 seats in section B and 11,300 seats in section C.

Step-by-step explanation:

write the equation of sphere volume:

\frac{4}{3} \pi  r^{3}

substitute the radius to the equation :

\frac{4}{3} \pi* 15^{3}

solve by calculator:

\frac{4}{3} \pi* 15^{3}=14137.17\\

≈14137.8 to the nearest tenth
