Answer:

x = 36

Step-by-step explanation:

Given

3(2x - 5) - 2x = 3(x + 7) ← distribute parenthesis on both sides

6x - 15 - 2x = 3x + 21

4x - 15 = 3x + 21 ( subtract 3x from both sides )

x - 15 = 21 ( add 15 to both sides )

x = 36

Answer:

-4

Step-by-step explanation:

I’m pretty sure

Answer:

Yes.

Step-by-step explanation:

The sum of the interior angles of triangles always add up to 180 degrees. The third angle of the top triangle would be 27. The third angle of the bottom triangle is 63.

Triangles are similar if the angles are the same. Therefore the 2 triangles are similar.

Hope that this helps!

Answer:

Is there more to this question?

For the first inequality, x > -1

For the second inequality, x < -1

Step-by-step explanation:

5x - 29 > -34

add 29 to both sides

5x > -5

divide both sides by 5

x > -1

-----------------------------------------------------

2x + 31 < 29

subtract 31 from both sides

2x < -2

divide both sides by 2

x < -1

Answer:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

[tex] \displaystyle \rm A_{ \text{c - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}[/tex]

let's figure out [tex]A_{\rm square}[/tex]:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times b \times h[/tex]

substitute h and b

[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times 4 \times 4[/tex]

reduce fraction:

[tex] \displaystyle A _{ \rm triangle} = 2 \times 4[/tex]

simplify multiplication:

[tex] \displaystyle A _{ \rm triangle} = 8[/tex]

likewise square

[tex] \displaystyle A _{ \rm squre} = {s}^{2} [/tex]

substitute s:

[tex] \displaystyle A _{ \rm squre} = {7}^{2} [/tex]

simplify square

[tex] \displaystyle A _{ \rm squre} = 49[/tex]

hence,

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =49- 8[/tex]

[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]

to figure out perimeter

let's figure out hypotenuse first

[tex] \displaystyle h = \sqrt{ {4}^{2} + {4}^{2} } [/tex]

[tex] \displaystyle h = \sqrt{ 16 + 16} [/tex]

[tex] \displaystyle h = 4 \sqrt{2} [/tex]

therefore,

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2} + 7 + 7[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2} + 14[/tex]

[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Answer:

$45.05

Step-by-step explanation:

Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50.  Nya has to pay 6% sales tax on this $42.50.  Thus, the final amount due is

(1.00 + 0.06)($2.50) = $45.05

Answer:

46.42

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 55 * 20%

= 55*.20

=11

Take the discount from the original price and that is the new price

new price = original price - discount

= 55-11

=44

Now we need to find the tax

tax = new price * tax rate

= 44 * 5.5%

= 44 * .055

=2.42

The final price is the new price plus the tax

final price = new price + tax

= 44+2.42

=46.42

Therefore, Nya will pay $46.42 for the sweater if she buys it.

Answer:

D. 735.25 cubic inches.

Step-by-step explanation:

Well hello there! My name is Lunako, and I'm here to help you out.

Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.

4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18  + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}

4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}

4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}

12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}

735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}

735.25 in³ {And with that this problem is solved.}

The volume of the sphere is 735.25 cubic inches, which is D.
