What is an expression?
In Mathematics, an expression can be defined as a mathematical equation which shows the relationship between two (2) or more numerical quantities such as being equal.
How to simplify the value of an expression?
In this exercise, we would simplify the given expression by solving the numerator and denominator respectively:
Numerator = 4(-8 + 4.5)
Numerator = 4(-3.5)
Numerator = -14.
For the denominator, we have:
Denominator = 6.25 + (-8.25)
Denominator = 6.25 - 8.25
Denominator = -2.
Substituting the parameters, we have;
[tex]\frac{4(-8+4.5)}{6.25+(-8.25)} = \frac{-14}{-2} \\\\\frac{4(-8+4.5)}{6.25+(-8.25)} =7[/tex]
