PLEASE HELP ME WITH THIS!

Mathematics
1 answer:

Answer:

EBC and ABE, as well as ABD and ABE

Step-by-step explanation:

Supplementary angles form an 180 degree angle. In other words, they form a straight line.

EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.

EBC and ABE form a straight line. So they are supplementary angles.

ABD  and ABE form a straight line. So  they are also supplementary angles.

CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.

So, EBC and ABE, as well as ABD and ABE are the correct choices.

Point R is on line segment QS. Given QS= 5x-2, QR= 3x-6, and RS=4x-2, determine the numerical length of RS.
pashok25 [27]

Answer:

The numerical length of RS is 10 units

Step-by-step explanation:

* <em>Lets explain How to solve the problem</em>

- Point R is on line segment QS

- The length of QS is (5x - 2)

- The length of QR is (3x - 6)

- The length of RS is (4x - 2)

- <em>The length of QS is the sum of the lengths of QR and RS</em>

∵ QS = QR + RS

∴ (5x - 2) = (3x - 6) + (4x - 2)

- Simplify the right hand side by adding like terms

∴ 5x - 2 = (3x + 4x) + (-6 + -2)

∴ 5x - 2 = 7x + -8 ⇒ (+)(-) = (-)

∴ 5x - 2 = 7x - 8

- Add 8 for both sides

∴ 5x + 6 = 7x

- Subtract 5x from both sides

∴ 6 = 2x

- Divide both sides by 2

∴ x = 3

- <em>To find the length of RS substitute the value of x in its expression</em>

∵ RS = 4x - 2

∵ x = 3

∴ RS = 4(3) - 2 = 12 - 2 = 10

∴ The numerical length of RS is 10 units

Write a simplified polynomial expression in standard form to represent the area of the rectangle below.
Marianna [84]
Area = Length * Width
A = (2x - 4) * (x + 5)
A = 2x² +10x-4x - 20
A = 2x² + 6x - 20

In short, Your Answer would be Option C

Hope this helps!

Write down all the subsets of {q,r,s}.
MrRissso [65]

{<em>q</em>, <em>r</em>, <em>s</em>} consists of 3 elements, so there are 2³ = 8 possible subsets.

• empty set: { }

• every possible singleton set: {<em>q</em>}, {<em>r</em>}, {<em>s</em>}

• every possible pair: {<em>q</em>, <em>r</em>}, {<em>q</em>, <em>s</em>}, {<em>r</em>, <em>s</em>}

• the set itself: {<em>q</em>, <em>r</em>, <em>s</em>}

A store sells laptops for $720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the n
Pani-rosa [81]

It would cost an employee $443.52 to purchase one of these laptops at the sale.

The selling price of the laptops is $720 each. The cost price is 20 percent more than the cost price.

Cost price = Selling price - 20% of cost price

Cost price = 720 - 20% * 720 = $576

At the release, the laptops are at 23% off the store's cost. Hence:

Price of laptop at release = 576 - 23% of 576

Price of laptop at release = $443.52

It would cost an employee $443.52 to purchase one of these laptops at the sale.
