Answer:
7 levels
Step-by-step explanation:
Let x = number of levels
⇒ 5.2 + 7.3x = 60
⇒ 7.3x = 60 - 5.2 = 54.8
⇒ x = 54.8 ÷ 7.3 = 7.5068...
Need to round down to whole complete levels, so number of levels you can play for free = 7
Answer:
Step-by-step explanation:
11 a).
20x + 5 + 24x - 1 = 180
44x = 176
x = 176 / 44
x = 4
b). 6x = 5x + 10
x = 10
Problem
The perimeter of a rectangle is less than 10 inches. The length is x and the width is x - 5. If the solution is x<5, ThEn the length is less than 5. Is this viable solution.
Solution
For this case the perimete rof a rectangle is given by:
P= 2x+2y
x= lenght y = width
And we also know that y= x-5
And replacing the condition given: P<10 we got:
2x +2y <10
2x +2(x-5)<10
4x -10 >10
And we can rewrite as:
4x >20
x>5
So then the best answer would be:
B. non viable
