The inequality is 45 + 2x < 120.
Solution:
Given a cost of video game = $45
Number of game controllers bought = 2
Each controller costs the same amount.
Total amount to spend = $120
Let x be taken the cost of game controller.
So, 45 + 2x < 120
Subtract 45 on both sides of the inequality.
⇒ 45 + 2x – 45 < 120 – 45
⇒ 45 – 45 + 2x < 120 – 45
⇒ 2x < 75
Divide by 2 on both sides of the inequality, we get
⇒
Hence, Kevin spend $ for each game controller.
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (5, - 8)
m = =
= 0
Volume of twin sized mattress =
39* 8.75* 75 = 25593.35 cubic inch
Volume of queen sized mattress =
60* 8.75* 80 = 42000 cubic inch
To fill 25593.35 cubic inch it takes 4 minutes
To fill 1 cubic inch it will take = minutes
So to fill 42000 cubic inch it will take =
= 6.56 minutes.
