A truck can be rented from Company A for $90 a day plus a $0.20 per mile .Company B charges $20 a day plus $0.70 per mile to ren
Alex787 [66]

The number of miles in a day at which the rental costs for Company A and Company B are the same is 140 miles

<h3>Rental cost</h3>

Let

  • Number of miles = x

Company A:

90 + 0.20x

Company B:

20 + 0.70x

  • Equate both rental cost

90 + 0.20x = 20 + 0.70x

90 - 20 = 0.70x - 0.20x

70 = 0.50x

  • Divide both sides by 0.50

x = 70/0.50

x = 140 miles

Therefore, the number of miles in a day at which the rental costs for Company A and Company B are the same is 140 miles

damaskus [11]

Answer:

7 7/12 pounds of fruit

Step-by-step explanation:

First, add all of the whole numbers

2 + 1 + 3= 6 (save for later)

1/3 = 4/12

5/6 = 10/12

4/12 + 10/12 + 5/12 = 19/12 or 1 7/12

now, add 1 7/12 + 6 to get you 7 7/12

hope this helps

Use FOIL and the distributive property to derive (a-b)^3​
Sergio039 [100]

Answer:

(a-b)^3 = \left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3

Step-by-step explanation:

(a-b)^3 = (a-b)(a-b)(a-b)

According to the perfect cube formula (a-b)^3 = \left(a-b\right)^3=a^3-3a^2b+3ab^2-b^3

And there you have it! The perfect cube formula already solved your equation!
