Answer:

5x+10y+5z.

Step-by-step explanation:

The given expression is

\dfrac{1}{2}(10x+20y+10z)

We need to find the equivalent expression by using the distributive property.

By using the distributive property, the given expression can be written as

\dfrac{1}{2}(10x+20y+10z)=\dfrac{1}{2}(10x)+\dfrac{1}{2}(20y)+\dfrac{1}{2}(10z)

=5x+10y+5z

Therefore, the required expression is 5x+10y+5z.

</span>Number 3:
<span>Positive Plus Positive Makes Larger Positive:
37 + 13 = 50</span>.
<span>So, 3 Is D.
Number 4:

s344n2d4d5 [400]

Answer: The player need to make 2 consecutive free throws to raise the average to 75%.

Step-by-step explanation:

Let the number of extra consecutive free throws to raise the average to 75% be 'x'.

Number of free throws already taken = 32

Number of attempts = 45

According to question, it becomes,

\dfrac{32+x}{45}=0.75\\32+x=45\times 0.75\\\\32+x=33.75\\\\x=33.75-32\\\\x=1.75

Hence, the player need to make 2 consecutive free throws to raise the average to 75%.
