# Evaluate variable expressions with rational numbers

Evaluate the expression 2+h for h = 0.5
Write your answer as a decimal or whole number.

Plug in h=0.5 and simplify

 2+h 2+0.5 Plug in h=0.5 2.5 Add

Evaluate the expression -2-3m for m=-1.4

Plug in m=-1.4 and simplify

 -2-3m -2-3(-1.4) Plug in m=-1.4 -2+4.2 Multiply 2.2 Subtract

Evaluate the expression t+|s| for $s=\frac{1}{10}$ and t=8.

$t+|s|=8+|\frac{1}{10}|=8+\frac{1}{10}=\frac{80+1}{10}=\frac{81}{10}$

Evaluate the expression 3+6f for f=-1.5
Solution: 3+6f=
