Question

If x=2, y=3 and z=1 then find the value of 1/2 x + 3/4 y

Answer 1

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 2

Answer:

decimal = 3.25

fraction = $\frac{13}{4}$

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

($\frac{1}{2}$ × (2)) +( $\frac{3}{4}$ × (3)) = 1 + 2.25 = 3.25 or $\frac{13}{4}$
