HELP ASAP!! How can you tell if three positive numbers form a Pythagorean triple?
Advocard [28]

The formula for the Pythagorean therom is: a[tex] a^{2} + b^{2} = c^{2}  

So, If a^{2} and b^{2} add up to c^{2} than it is a Pythagorean triple.

Which expression can be used to find the price of a $400 telescope after a 32% markup? Select all that apply.
emmainna [20.7K]

Answer:

Expressions C and D correctly determine the markup price.

Step-by-step explanation:

A markup in mathematics is when an object's price is raised by a certain percentage. Therefore, because we are told that the telescope is originally $400 and is marked up by 32%, we can actually mathematically evaluate this.

When you markup a price, you multiply the original price by 1+x, where x is the percentage at which the object is marked up. However, x needs to be in decimal form for it to work out.

\frac{32}{100} = \small\boxed{0.32}

Therefore, with this new decimal, we can add 1 to it.

1 + 0.32=\small\boxed{1.32}

Finally, we multiply this result by the original price.

1.32 \times 400=\small\boxed{528}

Therefore, we can already confirm that Expression C is one way to find the markup price.

  • We can eliminate expression A because it did not use the formula 1+x. It only uses the decimal form of the percentage.
  • We can eliminate expression B because the division to convert from the percentage form to the decimal form is flawed (the expression divided by 10 instead of 100) and also forgot to add 1 to the determined value.

Now, we can test the math for expressions D and E to see if either of these will equal $528.

Expression D is basically saying to add 32% of 400 to the original price. This would work out because we marked up the original price by 32%. Therefore, we can confirm that Expression D is also an expression that can be used to determine the markup price.

400 + 400(0.32)\\400(0.32) = 128\\400 + 128 = \small\boxed{528}

Finally, we also need to check expression E. This expression is saying to add the already marked up price to 400. This would not be correct.

400 \times 400(1.32)\\400(1.32) = 528\\400 \times 528 = \small\boxed{\$ 211,200}

Therefore, it has been determined that Expression C & Expression D are both equations that will find a markup price.

7x+8=-5x+32 can someone tell me what (x) is pls
WITCHER [35]

Hey there!

<u>Solve </u><u>the </u><u>equation </u><u>:</u>

  • Answer :

x = 2 ✅

  • Explanations:

7x + 8 = -5x + 32

<em>></em><em>></em><em> </em><em>Su</em><em>bstract </em><em>8</em><em> </em><em>from </em><em>e</em><em>ach </em><em>side </em><em>:</em>

7x + 8 - 8 = -5x + 32 - 8

7x = -5x + 24

<em>></em><em>></em><em> </em><em>Add </em><em>5</em><em>x</em><em> </em><em>to </em><em>both </em><em>sides </em><em>:</em>

7x + 5x = -5x + 24 + 5x

12x = 24

<em>></em><em>></em><em> </em><em>Divide </em><em>both </em><em>sides </em><em>by </em><em>1</em><em>2</em><em> </em><em>:</em>

12x / 12 = 24 / 12

x = 2

Therefore, your answer is x = 2
