Question

The table shows the heights of three monster trucks. Bigfoot 5 is 4.9 feet taller than Bigfoot 2. Write and solve an addition equation to find the height of Bigfoot 2.​

Answer 1

The height of Bigfoot 2 can be determined by writing an addition equation x + 4.9 = Height of Bigfoot 5 and then solving for x by subtracting 4.9 from the given height of Bigfoot 5.

Step-by-step explanation:

To find the height of Bigfoot 2, we can use the information that Bigfoot 5 is 4.9 feet taller than Bigfoot 2. If we let x represent the height of Bigfoot 2, then the height of Bigfoot 5 can be represented as x + 4.9 feet.

The equation we can write based on this information is:

x + 4.9 = Height of Bigfoot 5

Once we know the height of Bigfoot 5, we can insert that value into the equation and solve for x, which will give us the height of Bigfoot 2.

For example, if the height of Bigfoot 5 is given as 15 feet, the equation will be:

x + 4.9 = 15

To solve for x, subtract 4.9 from both sides:

• x + 4.9 - 4.9 = 15 - 4.9
• x = 10.1

So, the height of Bigfoot 2 would be 10.1 feet.

Answer 2

Height of Bigfoot 5 = Height of Bigfoot 2 + 4.9

Substituting the expressions we derived earlier, we get:

(x + 4.9) = x + 4.9

Simplifying the equation, we see that x cancels out on both sides, leaving us with:

4.9 = 4.9

This equation is true for any value of x, which means that we cannot determine the height of Bigfoot 2 from this information alone.

Therefore, we need additional information or data to solve for the value of x and determine the height of Bigfoot 2.
