Question

PLEASE HELP!!!!!! 

The table shows the hieghts of 3 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

Let
x = height of BigFoot 5
y = height of Bigfoot 2
We must write an expression that relates both heights:
y = (1 / 4.9) * x
Then, replacing the height of BigFoot 5
y = (1 / 4.9) * (15.4) = 3.14cm
answer
the height of Bigfoot 2 is 3.14cm
