Z scores are standard scores that describe the differences of individual values from the mean in units of

Use properties of logarithms to find the exact value of the expression. Do not use a calculator. \( \log _{6} 48-\log _{6} 8 \) \( \log _{6} 48-\log _{6} 8=\square \) (Type an integer or a simplified fraction.)

Use properties of logarithms to find the exact value of the expression. Do not use a calculator. \( \log _{12} 3+\log _{12} 4 \) \( \log _{12} 3+\log _{12} 4=\square \) (Type an integer or a simplified fraction.)

Solve the equation and check the solution. \( -5 x-8=22 \) \( x=\square \)

17. \( 7=5 y-13-y \)

Solve: \( 9(-a-6)-37=36 a-1 \)
