For the given values g = 15, h=2, the evaluation of the expression is obtained as 9.3.
What is an expression?
It is defined as the combination of constants and variables with mathematical operators.
It is given that, the expression is 0.9g - 2.1h and g = 15, h=2.
Substitute the value of g and h in order to evaluate the expression,
=0.9g - 2.1h
=0.9(15)-2.1(2)
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Thus, for the given values g = 15, h=2, the evaluation of the expression is obtained as 9.3.
