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

Solve -2(2x+5) -3(x-1)
OLEGan [10]
<h2>Hello!</h2>

The answer is:

-2(2x+5)-3(x-1)=-7x-7\\

<h2>Why?</h2>

To solve the problem, we need to perform the operations and then, add like terms.

We need to apply the distributive property, which is defined by the following way:

a(b+c)=ab+ac

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

3x+5x+x^{2}=8x+x^{2}

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.

So, we are given the expression:

-2(2x+5)-3(x-1)

Then, solving we have:

-2(2x+5)-3(x-1)=-4x-10-(3x-3)\\\\-4x-10-(3x-3)=-4x-10-3x+3\\\\-4x-10-3x+3=-4x-3x-10+3\\\\-4x-3x-10+3=-7x-7

Hence, we have that the answer is:

-2(2x+5)-3(x-1)=-7x-7\\

Have a nice day!
