Step-by-step explanation:
Given: The translated equation : 
To find the value of x if y = 87.5, we need to substitute the value of y in the given translated equation, we will get

Subtract 87.5 from both the sides , we get

Now, divide 300 on both the sides, we get

Answer:
FA = 25.87
Step-by-step explanation:
Given: BD = 30 , DF = 5 , EF = 16
To find: FA
Rectangular box is a Cuboid.
Figure attached.
AB = FE = 16
So,
In ΔADB
using Pythagoras theorem,

Again using Pythagoras theorem in Δ ADF we get

Therefore, FA = 25.87
