Write the expression in standard form. 27ℎ÷3ℎ

To write the expression \( \frac{27h}{3h} \) in standard form, you simplify it: \[ \frac{27h}{3h} = 9 \] The \( h \) terms cancel out, leaving: \[ 9 \] For the simplified expression representing \( A + B \), add the expressions: Expression A: \( 5q - r \) Expression B: \( -2q + 3r - 4 \) Combine like terms: \[ (5q - r) + (-2q + 3r - 4) \] \[ = 5q - 2q - r + 3r - 4 \] \[ = 3q + 2r - 4 \] So, the simplified expression for \( A + B \) is: \[ 3q + 2r - 4 \]
