Question

Irma watch a documentary about birds on Animal Planet today. The length of Irma's favorite bird is 36 inches longer than twice its wingspan. If the length of the bird is 214 inches, what's the wingspan of Irma's favorite bird?A. 107 inchesB. 356 inchesC. 178 InchesD. 89 inches

Answer 1

From the text, we can extract the followed equation:

`\text{length}=36\text{ + 2}*(\text{wingspan)}`

We know that the length is equal to 214 inches, so lets put this value in our equation:

`\text{length}=36\text{ + 2}*(\text{wingspan) }\Rightarrow\text{ 214}=36\text{ + 2}*(\text{wingspan) }\Rightarrow\text{214 - 36}=\text{ 2}*(\text{wingspan)}`

Continuing our calculation, we have:

`\text{178}=\text{2}*(\text{wingspan) }\Rightarrow\text{ }\frac{\text{1}78}{2}=(\text{wingspan) }\Rightarrow\text{89}=(\text{wingspan)}`

So our wingspan is 89 inches.
