You add 5 3/4 and 4 1/4 and your answer should be nine and 44
Answer:
let the third side be x
using pythagoras theorem we get
(7)^2+(6)^2=(x)^2
49+36=x^2
√(85)=x
x=9.21
Form an equation using the information provided
x = number
(x + 5)/9 = 3
multiply by 9
x + 5 = 27
then solve
x = 22
If you are looking for the sales tax then you take 89.75 times .075 this will give you 6.73 now you just add 6.73 to 89.75 and you get..
