Hello there!
The correct answer is C
-----------------------------
x - 3x = 2(4 + x)
Distribute the right side
x - 3x = (2)(4)+(2)(x)
x - 3x = 8 + 2x
Combine like terms
x - 3x - 2x = 8
-4x = 8
Divide both sides by -4
-4x/4 = 8/4
x = -2
Hence,
The correct answer is c
Have a nice day!
Answer: 18 gallons.
Step-by-step explanation:
Let's call the total gallons that the container can hold <em>x.</em>
<em> </em>Then, based on the information given in the problem, you can write the following expression:

Now, you must solve for x, as you can see below. Therefore, you obtain the following result:

Answer:
4 miles
Step-by-step explanation:
Let
x ----> the time to returned back biking in hours
d ---> the distance in miles
s ---> speed in miles per hour
Remember that
The speed or rate is equal to divide the distance by the time

The distance is equal to multiply the speed by the time

we know that

The distance to his friend's house and the distance of return is the same
so

solve for x

subtract 4x both sides



The total distance of the round trip is

substitute the value of x



Here we can simplify the product by multiply the square root 2 with square root 2 first.

=3*2
=6
So answer is 6
