1/4 of a number minus 8 is -23

Answer:

x = 3

Step-by-step explanation:

12 = 7x + 6 -5x        {Combine like terms}

12 = 7x - 5x + 6

12 = 2x + 6           {Subtract 6 from both sides}

12 - 6 = 2x

      6 = 2x                  {Divide both sides by 2}

    6/2 = 2x/2

3 = x

x = 3

Step-by-step explanation:

soltion

hotdog=50

people =6

dividing equally to each people

A person got=50/6

=8.33

so each got 8.33

but practically we cannot give it 8.33 to each so we can give 8 to each

Answer:

A is the answer

Step-by-step explanation:

Answer:

  23.  42 m^2

  24.  144 ft^2

  25.  68 cm^2

Step-by-step explanation:

The teacher should not need to spend any time teaching this. The area of the total figure is the sum of the areas of its parts. You already know that. And, you already know how to compute the areas of triangles and rectangles.

__

You may recall that the area of a triangle is ...

  A = 1/2bh

and the area of a rectangle with the same base and height is ...

  A = bh

So, a triangle with base b and height h has the same area as a rectangle with the same base (b) and half the height (h/2). Recognizing this makes these problems really simple.

__

23. The base of the rectangle and triangle is 7 m. The height of the triangle is 4 m, so its area is equivalent to adding 4/2 = 2 m to the 4 m height of the rectangle. Then the total area is ...

  A = (7 m)(4 m +(1/2)(4 m)) = (7 m)(6 m) = 42 m^2

__

24. Since there are two identical triangles of height 5, their total area is equal to that of a rectangle of height 5.

  A = (12 ft)(7 ft +5 ft) = 144 ft^2

__

25. The 5 cm height of the triangle makes it have an area equivalent to a rectangle 5/2 cm high.

  A = (8 cm)(6 cm +5/2 cm) = 68 cm^2

Note: we have read the fuzzy numbers as 8 cm wide, 6 cm high for the rectangle, and 5 cm high for the triangle. If your figure is different, please use the appropriate numbers in the calculation.

Answer:

Per pretty much means 1. So for example if I say I'm going 12 miles PER hour it means 12 miles every 1 hour.

Answer:

The value is 9.7

Step-by-step explanation:

Use the Pythagorean theorem. [tex]a^{2} + b^{2}= c^{2}[/tex]

a=7 b=x c=12

[tex]7^{2} + x^{2}= 12^{2}[/tex]

[tex]49+x^{2} =144[/tex]

[tex]144-49=95[/tex]

[tex]x^{2} =95[/tex]

[tex]\sqrt{ x^{2}} =\sqrt{95}[/tex]

x=9.74679434481

x=9.7

Answer:yes

Step-by-step explanation:

Answer:0.3293

Step-by-step explanation:

Let the smallest integer equal x - 1, the next one equal x, and the last one equal x + 1.

4(x-1) = 3(x-1) + 6

x-1 = 5

x = 6

The smallest integer is x - 1, which is equal to 5. Thus, the smallest of the three integers is 5.

h = 15√3/4

= 6.4875

≈ 6.5 cm

h = 3x

c₁ = 5 cm

c₂ = x

h² = c₁² + c₂²

(3x)² = 5² + x²

9x² = 25 + x²

8x² = 25

x² = 25/8

x = √25/8

x = 5/2√2

x = 5√2/4

h = 3x

= 3×5√2/4

= 15√2/4 cm

Answer:

Step-by-step explanation:

Explanation:

Choice A isn't the answer because we don't know anything about the angles, so we can't use the AA (angle angle) Similarity theorem.

Choice B isn't the answer because we don't have info about all three pairs of sides (we only have two pairs of sides).

Choice C isn't the answer in a similar way choice A isn't either. We don't know anything about the angles, so we can't use the "A" in "SAS".

Choice D is the only thing left. It turns out we don't have enough info to be able to determine if the triangles are similar or not.

Answer:

[tex]GH=2\sqrt{10}[/tex]

Step-by-step explanation:

Considering each is square is 1x1.

We have the points G(-2, -3) and H(0, 3).

Using the distance formula:

[tex]$d=\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$[/tex]

[tex]$d=\sqrt{(-2 - 0)^2 + (-3 - 3)^2}$[/tex]

[tex]$d=\sqrt{(-2 )^2 + (-6)^2}$[/tex]

[tex]$d=\sqrt{4 +36}$[/tex]

[tex]d=\sqrt{40}=2\sqrt{10}[/tex]

Also, using the Pythagorean theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]2^2+6^2=c^2[/tex]

[tex]4+36=c^2[/tex]

[tex]c=GH=\sqrt{40}=2\sqrt{10}[/tex]

Answer:

multiply both sides by [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] x - 8 = 12

first step

Add 8 to both sides

[tex]\frac{2}{3}[/tex] x = 20

second step

Multiply both sides by [tex]\frac{3}{2}[/tex] to clear the fraction

x = [tex]\frac{3}{2}[/tex] × 20 = 30

Since PQ = QR = RS,

Let's set PQ equal to RS

2x + 3 = x + 10

Subtract x and 3 from both sides.

x = 7

PQ = 2x + 3 = 2(7) + 3 = 14 + 3 = 17

Since PQ = QR = RS,

QR = 17

Answer:

$1,423.08

Step-by-step explanation:

[tex]\frac{37000}{26} = 1,423.076[/tex] rounded to the nearest cent it becomes 1,423.08.

*Remember that there are 26 biweekly periods in a year. Divide her annual salary (37,500) by 26.

The biweekly salary, rounded to the nearest cent is 1,423.08.

It is required to find the solution.

A number that is easily multiplied, divided, etc., and especially a number that ends in zero.

Given :

Christina is paid biweekly. Her annual salary is 37,500.

According to given question we have,

We know that there are 26 biweekly periods in a year. Divide her annual salary (37,500) by 26.

37500/26=1423.076

Rounded to the nearest cent it becomes 1,423.08.

Therefore, the biweekly salary, rounded to the nearest cent is 1,423.08.

#SPJ6

Answer:

Step-by-step explanation:

et A=120°

and B=5Pi /6

Pi radians ---------> 180°

  x<----------------------- 120°

so x =120 x Pi / 180 = 12 xPi / 18 = 2 Pi/3

so A = 2Pi / 3 radian  

let 's compare A and B

we know that 5Pi /6 = 0.8 Pi and  2P/3= 0.6 Pi, 0.8>0.6,  

finally 5Pi /6 > 2P/3

so B>A
