Table show step by step how do you simplify the algebraic expression 3(x-5)+4x. <br>Justify step 4​
ale4655 [162]
<h3>Answer: Commutative Property (choice C)</h3>

===================================================

Explanation:

Here are all of the justifications for each step

  • Step 1. None needed. This is the original expression
  • Step 2. Distributive property
  • Step 3. Multiply  (the 3 and 5 multiply to 15)
  • Step 4. Commutative property. Specifically, this is the commutative property of addition which allows us to add any two numbers in any order we want. In this case, the  -15 and 4x terms swap places.
  • Step 5. Associative property. The parenthesis group the first two terms away from the third term.
  • Step 6. Combine like terms. Both 3x and 4x have an x only so they are like terms that combine to 7x. You can think of it as 3+4 = 7, then you just tack an x onto everything to get 3x+4x = 7x.

Brett golfs for the forestville knights high school team. When he practices his putting, he can make a 10-foot putt 80% of the t
balu736 [363]
The formula to calculate standard deviation from probability is \sqrt(n*p*(1-p)). n is the sample size, and 200 in this case (number of putts for practice). p is 80% or 0.8, the probability that he can make it. So the standard deviation is \sqrt(200*0.8*(1-0.8)=\sqrt(200*0.8*0.2)=\sqrt(16)=4.

If you have 80 employees and you grew 116%, what was the amount of original employees?
Nezavi [6.7K]

Answer: 69

Step-by-step explanation:

Let the original employee be x , this means that

116% of x = 80

\frac{116x}{100} = 80

116x = 8000

divide through by 116

x = 8000/116

x = 68.96551724

Since we are dealing with employees , therefore x ≈ 69

This means that there were 69 employees originally
