All you have to do is plug in the given values for a and b.
0.9a - 1.5b = ?
a = 15
b = 3
0.9 (15) - 1.5 (3)
= 13.5 - 4.5
= 9
Note:
•Integers are whole numbers.
For ex: 1, 2, 3, 4...
•Decimals have a period in between 2 numbers
For ex: 0.1, 0.2, 0.3
Sometimes when it’s concerning significant digits then decimals could also be
1.0, 2.0, 3.0 ... I wouldn’t worry about this right now until you get into higher years

You can use the special right triangles for this equation. Since the side lengths are 3 and 4, the hypotenuse of the triangle would be 5, or you can use the equation a2 + b2 = c2, 3^2 + 4^2 = c2, 25 = c2, c=5
