Answer:
Distributive property
Step-by-step explanation:
Think of Distributive property being a party. the host is outside of the house (the parenthesis) and wants to greet everyone at the party. so 2x3k=6k and 2x5=10. so you replace 2(3k+5) with 6k+10
Answer: x=-3 and y= -15
Step-by-step explanation: 1 Substitute y=5xy=5x into 4x-2y=184x−2y=18.
-6x=18
−6x=18
2 Solve for xx in -6x=18−6x=18.
x=-3
x=−3
3 Substitute x=-3x=−3 into y=5xy=5x.
y=-15
y=−15
4 Therefore,
\begin{aligned}&x=-3\\&y=-15\end{aligned}
x=−3
y=−15

Answer: 8</h3>
=====================================================
Explanation:
According to the table, 10 people have brown eyes. This is out of 1+10+1+1+7 = 20 people total. So 10/20 = 0.50 = 50% of the group has brown eyes.
If this trend holds up, then we expect 50% of the next group of 16 people also have brown eyes.
50% of 16 = 0.50*16 = 8
We expect 8 people to have brown eyes in this next group. This is of course assuming that the first group is unbiased and represents the population (or is close enough).

Answer:
a. 
b. 
Step-by-step explanation:
You have the following formula given in the exercise:
a. If the object is 50 feet above the ground, you can identify that the value of the variable "h" would be the following:
Then, knowing that value, you can substitute it into the given formula and then evaluate in order to calculate the time in seconds for the object to be 50 feet above the ground.
This is:
b. When the object reaches the ground, the value of "h" is:
Therefore, substituting this value into the formula and evaluating, you get that time (in seconds) it takes to the object reaches the ground is:
