Q. Select all of the equations below that are equivalent to:z+2=7Use properties of equality.Multi-select Choices:(A) −33z+−99=−33⋅7(B) 2z+6=2⋅7(C) 32z+64=32⋅7(D) −23z+−92=−23⋅7
Check Equation (A): To determine if the equations are equivalent, we need to check if they can be simplified or transformed into the form z+2=7 by using properties of equality, such as multiplication or division by the same non-zero number on both sides of the equation.
Check Equation (B): Let's start with option (A): −33z+−99=−33⋅7We can simplify this by dividing both sides by −33 to see if we get the original equation.−33z/−33+−99/−33=−33⋅7/−33z+3=7This is not equivalent to z+2=7 because the constant term is different.
Check Equation (C): Now let's check option (B): 2z+6=2⋅7Divide both sides by 2 to see if it simplifies to the original equation.22z+26=22⋅7z+3=7This is also not equivalent to z+2=7 because the constant term is different.
Check Equation (D): Next, let's examine option (C): 32z+64=32⋅7 Divide both sides by 32 to check for equivalence. 3232z+3264=3232⋅7z+2=7 This is equivalent to the original equation z+2=7.
Check Equation (D): Next, let's examine option (C): 32z+64=32⋅7 Divide both sides by 32 to check for equivalence. 3232z+3264=3232⋅7z+2=7 This is equivalent to the original equation z+2=7.Finally, let's look at option (D): −23z+−92=−23⋅7 Divide both sides by −23 to check for equivalence. −23−23z+−23−92=−23−23⋅7z+4=7 This is not equivalent to z+2=7 because the constant term is different.
