Answer:
-45-26x+30
Step-by-step explanation:
So first you let's divide this equation into three parts.
Part one -9x(5x+4)
- Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45 and -9x*4 = -36x
- Step two: Put the answers together. That would leave us with -45-36x.
Part two 10(x+3)
- Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30
- Step two: Put the answers together. That would leave us with 10x+30
Part three solve
- Step one: combine and put together what you have solved for. That would leave us with a -45-36x+ 10x+30
- Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.
- Step three: Write the equation in standard form. Therefore the answer is -45-26x+30.

Probabilities are used to determine the chances of events
The probability that Jill selects a wooden pencil and then a mechanical pencil is 8%
<h3>How to calculate the probability</h3>
Represent the events as follows:
- A represents mechanical pencil
- B represents wooden pencil
- C represents colored pencil
So, we have
P(A) = 20%
P(B) = 40%
P(C) = 30%
The probability that Jill selects a wooden pencil and then a mechanical pencil is then calculated as:
P(B n A) = P(B) * P(A)
This gives
P(B n A) = 40% * 20%
Evaluate the product
P(B n A) = 8%
Hence, the probability that Jill selects a wooden pencil and then a mechanical pencil is 8%

Answer: Ricky: 1204, Pedro: 1481
Step-by-step explanation:
If Pedro hit 277 more base hits that Ricky, and together they hit 2685, then
2685=2x+277
2x=2408
x=1204
so Ricky hit 1204 base hits and Pedro hit 1481.
check: 1204+1481=2685
<u>use the distance formula for this which is:
Sqrt[ (x2-x1)^2 + (y2-y1)^2]
If that is hard to read look it up but pretty much its:
Sqrt [(-12 -12)^2 + (-2-5)^2]
Sqrt [(0)^2 + (-7)^2]
Sqrt [49]
7</u>
Good answer is -1:) have a good day;)
