Multiply out the bracket:
(-1/2×-3y)+(-1/2×10)
-1/2×-3= 1.5 as the negatives cancel out
-1/2×10= -5
So the answer is 1.5y-5 or 3/2y-5 if you prefer a fraction

Answer:

\frac{3}{2}(y)-5

Step-by-step explanation:

The given expression is

-\frac{1}{2}(-3y+10)

We need to find the expanded form of given expression.

According to distributive property, if a,b and c are three real numbers then

a(b+c)=ab+ac

Using distributive property, the given expression can be written as

-\frac{1}{2}(-3y)-\frac{1}{2}(10)

On further simplification we get

\frac{3}{2}(y)-5

Two terms are called like terms if they have same variable of same power.

In the above expression we do not have like terms.

Therefore, the expanded form of given expression is \frac{3}{2}(y)-5.

Which is the corresponding angle
velikii [3]

Answer:

<h2>4 and 8</h2>

Step-by-step explanation:

4 and 8 are corresponding angles as they form at parallel lines cut by a transversal.

4 and 3 are supplementary angles (they both add up to 180°).

4 and 1 are vertically opposite angles and are equal to each other.

<u>From the above explanations, only 4 and 8 are corresponding angles. </u>

Can someone help me asap

Answer:

Option Y is correct.

Step-by-step explanation:

We are given the table representing the relation between new students and returning students for difference classes.

It is required to form the relative frequency table for the given situation.

So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.

<em>Thus, we will get the relative frequency table by dividing the given table values by 500.</em>

Hence, we will get the following table,

                          New Students               Returning Students           Total

10th                         0.01                                   0.34                             0.35

11th                          0.006                                0.324                           0.33

12th                         0.004                                0.316                            0.32

Total                        0.02                                  0.98                                1

Thus, option Y is correct.
