Final Answer: 5x - 30

Steps/Reasons:

Question: Simplify 5(x - 6)

<u>Step 1</u>: Expand by distributing the terms.

5x + 5 × -6

<u>Step 2</u>: Simplify 5 × -6 to -30.

5x - 30

~I hope I helped you :)~

Our equation looks like:

5(x-6)

This means that we will need to distribute. This means that we need to multiply everything inside the parenthesis by the number outside of the parenthesis. (<em>Note: you only distribute when variables are involved.)</em>

(5 \cdot x)-(5 \cdot 6)

Simplify:

5x-30

We cannot simplify any further, so we know that our equation, until we know what x equals, is 5x - 30.

Alonzo invested his savings in two investment funds. The amount he invested in Fund A was $2000 less than the amount he invested
alina1380 [7]

Answer:

There were $13,200 in Fund B.

Step-by-step explanation:

We are given the following in the question:

Let x be the amount in Fund A and y be the amount in Fund B.

The amount he invested in Fund A was 2000$ less than the amount he invested in Fund B.

Thus, we can write the equation:

x = y -2000

Profit percent on Fund A = 7%

Profit percent on Fund B = 8%

Total profit = $1960

Thus, we can write the equation:

7\%(x) + 8\%(y) = 1960\\7x + 8y = 196000

Solving the two equations by substitution, we get,

7(y-2000) + 8y = 196000\\\Rightarrow 15y = 198000\\\Rightarrow y = 13200\\\Rightarrow x = 11200

Thus, there were $13,200 in Fund B.

What is the solution to the system of equations ?
Fudgin [204]

Answer:

A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.

Question about a rational expression
sesenic [268]
-9=6/v

You have to multiply v both sides because
6/v x v = 6 and helps you get rid of the v on the right side.
If you multiply by 6, 6/v x 6 = 36/v, that’s why it don’t work.

Answer:
-9=6/v
-9v=6
v=-6/9
v=-2/3

Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.
lapo4ka [179]

Multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

<h3>How to verify if a triangle form Pythagorean triple?</h3>

Pythagoras's principle follows the rule:

c² = a² + b²

where

  • a and b are the legs
  • c is the hypotenuse side.  

Therefore, Pythagorean triples are a² + b² = c² where a, b and c are the three positive integers. The most known and smallest triplets are (3,4,5).

If we reduced the length of the side of the triangle with the greatest common factor, it should give us 3, 4, 5.

Hence,

21, 28 and 35 has greatest common factor as 7

21 / 7 , 28 / 7 and 35 / 7

3, 4, 5

Hence, multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.
