If you double president Reagans age at the time of his first inauguration and subtract his age at the time he died, the result is 45 years. How old was president Reagan when he died?

93

Step-by-step explanation:

Let's say President Reagan was x years old when he died. He was 69 years old at his first inauguration

(2*69)-x = 45

Wait. But how will we find x in that equation?

--> (2*69)-45 = x

That's better.

2*69 = 138

138-45 = 93

x=93

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
