solve the equation 1/2x+7=18

Answers

Answer 1

Answer: 22

Step-by-step explanation:

Solve for x

   1/2x + 7 = 18

Combine 1/2 and x.

  x/2+ 7 = 18

Move all terms not containing x to the right side of the equation.

Subtract 7 from both sides of the equation.

  x/2= 18 − 7

  x/2 = 11

Multiply both sides of the equation by 2.

  2 ⋅ x/2 = 2 ⋅ 11

Simplify both sides of the equation.

Cancel the common factor of 2.

  x = 2 ⋅ 11

Multiply 2 by 11.

  x = 22

Answer:

[tex]V=2197\ cm^3[/tex]

Step-by-step explanation:

Surface Area and Volume of a Cube

Given a cube of side length a, the surface area is:

[tex]A = 6a^2[/tex]

The volume is calculated as:

[tex]V=a^3[/tex]

It's given the surface area of a cube:

[tex]A=1014\ cm^2[/tex]

We can find the side length a by solving for a:

[tex]\displaystyle a=\sqrt{\frac{A}{6}}[/tex]

[tex]\displaystyle a=\sqrt{\frac{1014}{6}}[/tex]

[tex]\displaystyle a=\sqrt{169}[/tex]

a = 13 cm

Now compute the volume:

[tex]V=13^3[/tex]

[tex]\boxed{V=2197\ cm^3}[/tex]

Answer: a) 2197 cm^3

Answer:

Adam: 52.26°

Step-by-step explanation:

Use Cosine Rule, [tex] Cos(C) = \frac{a^2 + b^2 - c^2}{2ab} [/tex], to find the angle of both players.

✔️Angle of Carlos:

Let the angle be C,

a = 50 ft

b = 40 ft

c = 24 ft

Plug in the values into the equation

[tex] Cos(C) = \frac{50^2 + 40^2 - 24^2}{2*50*40} [/tex]

[tex] Cos(C) = \frac{3,524}{4,000} [/tex]

[tex] C = Cos^{-1}(\frac{3,524}{4,000}) [/tex]

C = 28.24° (nearest hundredth)

✔️Angle of Adam:

Let the angle be C,

a = 30 ft

b = 22 ft

c = 24 ft

Plug in the values into the equation

[tex] Cos(C) = \frac{30^2 + 22^2 - 24^2}{2*30*22} [/tex]

[tex] Cos(C) = \frac{808}{1,320} [/tex]

[tex] C = Cos^{-1}(\frac{808}{1,320)} [/tex]

C = 52.26° (nearest hundredth)

Find the missing endpoint if the midpoint is at (2,-5) and one endpoint is at (12,-5).
O (2,-5)
O(-8,-5)
O(10-8)
O (12,-5)

Answers

Answer:

The answer is (-8,-5)

Step-by-step explanation:

Since the midpoint is (2, -5), the 2 endpoints should be equidistant from each other. Since  the endpoint that is given (12, -5), is 10 points to the right of the midpoint, the second midpoint should be 10 points to the left of it. 2-10=-8

Therefore, the other midpoint is (-8,-5)

you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)

(x-8)2 – 7 = 25
Factored

Answers

Answer:

x = 8 ± 4√2

Step-by-step explanation:

(x - 8)² - 7 = 25

Add 7 to both sides.

(x - 8)² = 32

Take the square root for both sides.

x - 8 = ±√32

Add 8 to both sides.

x = 8 ±√32

Simplify √32

√32 = √16 · √2

√32 = ±4√2

x = 8 ± 4√2

[tex] \arc{PNM} = 222 [/tex]

Step-by-step explanation:

Central angle = measure of the arc it subtends

Therefore:

[tex] \arc{PN} = \arc{PM} = 138 [/tex]

A full circle = 360°

So,

[tex] \arc{PN} + \arc{PM} + \arc{NM} = 360 [/tex]

Plug in the values

[tex] 138 + 138 + \arc{NM} = 360 [/tex]

[tex] 276 + \arc{NM} = 360 [/tex]

[tex] \arc{NM} = 360 - 276 [/tex] (subtraction property of equality)

[tex] \arc{NM} = 84 [/tex]

[tex] \arc{PNM} = \arc{NM} + \arc{PN} [/tex]

Plug in the values

Similar Triangles

If two triangles are similar, then:

* All the corresponding side lengths are proportional by the same scale factor

* All the internal angles are congruent.

The image provided in the question has two similar triangles TYZ and TWX. We have completed the shape with a variable p =TZ, whose value will be determined by applying the first similarity condition above.

The ratio between the heights is 20:16, and the proportion between the bases is (6+p):p, thus:

[tex]\displaystyle \frac{6+p}{p}=\frac{20}{16}=\frac{5}{4}[/tex]

Cross-multiplying denominators:

4(6 + p) = 5p

24 + 4p = 5p

Solving for p:

p = 24

Then, TZ = 24
