For this case, the first thing we must do is define the variable x. We have then, that according to the statement of the problem: x = Weight of firefighter in pounds. We now write the equation that fits the problem. We have the following information: "a firefighter uses equipment that weighs 60 pounds." The firefighter weighs x pounds " Thus: t = x + 60 Answer: An equation that can be used to find the total weight of both the fighter and his equipment is: t = x + 60
I can't seem to find a good way to make it more connected so I'll just have to tell you. The ∞ is above the ∑, while the i = 1 is under it. That is all one thing. The rest is followed as normal, and it is all next to the ∑
It isn't different, it is very much the same 1-1 = 0 .1-.1 = 0 5.25 - 3.75 = 1.50 1.0005 +1.005 = 2.0055 just make sure to line the decimal places on top of each other <span />
