STEP 1

Assumptions1. The value of $x$ is8. The value of $y$ is3

STEP 2

Let's start by evaluating the first expression $12-y$ by substituting $y=$.
$$12-y =12-$$

STEP 3

Calculate the value of the first expression.
$$12-y =12-3 =9$$

STEP 4

Now, evaluate the second expression $3x-y$ by substituting $x=8$ and $y=3$.
$$3x-y =3*8-3$$

STEP 5

Calculate the value of the second expression.
$$3x-y =3*8-3 =21$$

STEP 6

Next, evaluate the third expression $4y-10$ by substituting $y=3$.
$$4y-10 =4*3-10$$

STEP 7

Calculate the value of the third expression.
$$4y-10 =4*3-10 =2$$

STEP 8

Finally, evaluate the fourth expression $\frac{1}{4}xy$ by substituting $x=8$ and $y=3$.
$$\frac{1}{4}xy = \frac{1}{4}<em>8</em>3$$

STEP 9

Calculate the value of the fourth expression.
$$\frac{}{4}xy = \frac{}{4}<em>8</em>3 =6$$

Now, match each expression to its value.
. $12-y =9$
2. $3x-y =21$
3. $4y-10 =2$
4. $\frac{}{4}xy =6$
So, the correct matches are. $12-y$ matches with $9$
2. $3x-y$ matches with $21$
3. $4y-10$ matches with $2$
4. $\frac{}{4}xy$ matches with $6$
