2x - 6 = 18
2x = 18 + 6 (24)
2x = 24
x = 12
<span>3x + 9 = 2x + 24
3x + 9 = 2x + 24 - 9 (2x + 15)
3x = 2x + 15
3x - 2x = 15
x = 15
</span><span>4x = 2.4? 0.4x = 2.4? I can't tell what the question is. Let me know in the comments and I'll answer it.
</span>
<span>5x + 4 = 24
5x = 24 - 4 (20)
5x = 20
x = 4
</span><span>2x / 3 = 4
2x = 4 * 3 (12)
x = 6
</span><span>3(x + 7) = 51
3x + 21 = 51
3x = 51 - 21 (30)
3x = 30
x = 10
Hope I helped :)</span>

Step-by-step explanation:
Answer:
B(75) represents the percent of battery full after 75 minutes of game play
Step-by-step explanation:
Let m represent the number of minutes of game play. If 1% of the battery is drained every five minutes of game play, then after m minutes of game play 
was drained.
The battery starts off at 80% full. After m minutes the battery will have
percent full.
When 
minutes, then
A₁ = 3
a₂ = 4.2
d = a₂ - a₁
= 4.2 - 3
= 1.2
a₉₈ = a₁ + d(n-1)
= 3 + 1.2(98-1)
= 3 + 1.2×97
= 3 + 116.4
= 119.4
