Answer:

1 1/4

Step-by-step explanation:

x=2, y=3, and z=1

1/2(2)+3/4(3)=1+3/12=1 1/4

Answer:

decimal = 3.25

fraction = [tex]\frac{13}{4}[/tex]

Step-by-step explanation:

since x and y are the only 2 variables being expressed in the question then it makes "z" irrelevant.

Therefore, you just need to plug in x and y into your question

([tex]\frac{1}{2}[/tex] × (2)) +( [tex]\frac{3}{4}[/tex] × (3)) = 1 + 2.25 = 3.25 or [tex]\frac{13}{4}[/tex]
