38+3x=89 is the proper way to write this equation.
<em>Now to solve, first subtract 38 from both sides</em> (38-38 and 89-38)
3x=51
<em>Now divide both sides by 3</em>( 3x/3 and 51/3)
x=17
Answer:
15.3feet
Step-by-step explanation:
Given the scale model of a train as;
2cm = 3feet
We are to find the height of real train of height 10.2cm, we can write;
10.2cm = x
Divide both expressions
2/10.2 = 3/x
2x = 3×10.2
2x = 30.6
x= 15.3
Hence the height if the real train is 15.3feet
