Which of the expressions are equivalent to the one below? Check all that apply.
3. (2 + 6) + 4.5
A. (6+2): 3+ 4.5
B. 3.2 + 3.6+4.5
O C.3.2 + (6 + 4): 5
D. 5·4+3.(6+2

Substitute the vales for the variables: (3/2)(4/1)-3+(5/3)(3/1) Follow PEMDAS rules. Multiply first. (3/2)(4/1)=12/2 =6 (5/3)(3/1)=15/3=5. So, the expression is now: 6-3+5. Now, add and subtract from left to right. 6-3+5 = 3+5
