When 27 times x squared times z all over negative 3 times x squared times z to the fourth power is completely simplified, the exponent on the variable z is

numerical answers ?

The solution would be like this for this specific problem:

27×x2×z/−3×x2×z4
=−9×x2×z/−3×x2×z3
=−9/z3
=−9z−3

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
