4 0

Answer:

0

Step-by-step explanation:

If we set up an equation, we get:

2x+1 = 2x-4

We subtract 2x from both sides and get:

1 = -4

That is FALSE, so that means there are NO solutions

RSB [31]

Answer:

This question is incomplete as no image was attached. Please find the missing image in the attachment. Also, this is the correct question:  

Cal's go cart has a gas tank with the dimensions shown below. He uses a gas can that holds 1 gallon of gas, to fill the go cart tank. 1 gallon = 231 inches^3. How many full gas cans will it take to fill the go cart's gas tank?

Answer: 2 full gas cans

Step-by-step explanation:

From the image, we have the following dimensions:

length, l = 15.4 inches (in)

width, w = 10 in

height, h = 3 in.

The volume of the gas tank (which is rectangular) is given as:

Volume = length * width  * height = lwh\\\\Volume = 15.4 * 10 * 3 = 462 cubic inches = 462in^{3}

NB: The unit of volume is cubic units. In this example, it is cubic inches.

The gas can being used to fill the tank holds 1 gallon of gas = 231in^{3}

The total volume to be filled is 462in^{3} of gas.

So, it will take  \frac{462in^{3} }{231in^{3} } = 2  full gas cans to fill the go cart's gas tank.

Therefore, the answer is 2.
