Answer:
Chad's claim is incorrect
Step-by-step explanation:
The homework problems that complete the question are:
[tex]3x^2.2x^4[/tex]
[tex]5 - 2x = 3x[/tex]
[tex]3(2x + 7)[/tex]
[tex]7x^2 +2x -3x^2 -9[/tex]
[tex]\frac{2}{3} = \frac{x+2}{6}[/tex]
Required
Is Char right?
From the homework problems above, there are 5 mathematical problems
So:
Chad's claim that he had 5 equations.
A mathematical expression is an equation if it has an = sign
So for Chad's claim to be correct; at least 4 of the mathematical problems must have an = sign
By the explanation done above, we have the following observations
[tex]3x^2.2x^4[/tex] -> No Equation
[tex]5 - 2x = 3x[/tex] -> Equation
[tex]3(2x + 7)[/tex] -> No Equation
[tex]7x^2 +2x -3x^2 -9[/tex] -> No Equation
[tex]\frac{2}{3} = \frac{x+2}{6}[/tex] -> Equation
Apparently, only 2 of the 5 problems are equation.
Hence, Chad's claim is incorrect.
