Answer:

x is the variable

Step-by-step explanation:

Given the following equation:

[tex]\frac{300+200}{x}[/tex]

The term variable is basically a symbol or a letter that will change throughout the completion of a equation. In this case we are solving for x which means x is the letter/symbol that will change throughout the completion of this equation which means "the letter x is the variable."

Hope this helps.

Check the picture below.  Recall that a full circle has 360°.

[tex]\boxed{19}\\\\ \cfrac{359-27x}{2}=12x+1\implies 359-27x=24x+2\implies 359=51x+2 \\\\\\ 357=51x\implies \cfrac{359}{51}=x\implies 7=x \\\\\\ \boxed{20}\\\\ \stackrel{\widehat{QR}}{359-27x}\implies 359-27(7)\implies 170[/tex]

Step-by-step explanation:

Answer:

  880 cm²

Step-by-step explanation:

Extending the vertical segments divides the figure into three rectangles:

  left: 7 cm by 13 cm

  middle: 38 cm by 18 cm . . . . . (overall height is 8+7+23 = 38 cm)

  right: 21 cm by 5 cm

The total area is the sum of the areas of these rectangles. Each area is the product of the rectangle dimensions.

  A = (7 cm)(13 cm) +(38 cm)(18 cm) +(21 cm)(5 cm) = (91 +684 +105) cm²

  A = 880 cm²

Answer:

2800

Step-by-step explanation:

The closest 100 to 2775 is 2800

Answer:

The answer is 2800

Step-by-step explanation:

Now,

2775

Here, The last digit is 5 and last second digit is 7 which is more than 5

So, write 0 at the place of 5 and add 1 to the 7 i.e., 7 + 1 = 8 we get, 2780

Again, The last second digit is 8 and last third digit is 7 which is more than 5

So, write 0 at the place of 8 and add 1 to the 7 i.e., 7 + 1 = 8 we get, 2800

Thus, The answer is 2800

If you want to know it's nearest thousand value than the value will be 3000.

Answer:

98°

Step-by-step explanation:

m∠1 = m∠2

5x + 12 = 7x - 16; substitute the given

2x = 28

x = 14

m∠2 + m∠3 = 180; supplementary angles

82 + m∠3 = 180

m∠3 = 180 - 82

m∠3 = 98 degrees

Answer: m<3 = 98

Explanation: If two parallel lines are cut by a transversal,

then alternate interior angles are congruent.

This means that the m<1 = m<2.

So we can setup the equation 5x + 12 = 7x - 16

and solving this equation gives us x = 14.

Now let's use <2 to help us find the m<3.

Since x = 14, we can plug a 14 into the equation for x

to find the m<2 and this gives us 7(14) - 16 which is 82.

Now, we know that <2 and <3 form a straight

angle which is equal to 180 degrees.

So we can say that 82 + m<3 = 180 and we find that m<3 = 98.

Answer:

The system of linear equations is x + y = 64 and x = y + 14.

Given that,

The total number of students is 64 .

Here we assume the x be the number of students in filmmaking club .

And, y be the number of students in yearbook club.

Based on the above information, the calculation is as follows:

x + y = 64

And,

x = y + 14

Therefore,

We can say that

Number of students in yearbook club = 25

And, the number of students in filmmaking club = 39

Answer:

304.8 m2 should be the right answer

have a good day

Answer:

A   304.8 cm²

Step-by-step explanation:

lateral area = perimeter of the base × height

perimeter of the base = 2(5.2 cm + 7.5 cm) = 2(12.7 cm) = 25.4 cm

lateral area = 25.4 cm × 12 cm = 304.8 cm²

Answer:

[tex]x = - \frac{5}{8} [/tex]

Step-by-step explanation:

[tex] {x}^{2} + 4x = - {y}^{2} + 6[/tex]

[tex] {x}^{2} + 4x + {y}^{2} - 6 = 0[/tex]

Standard Form of Conic is

[tex]ax {}^{2} + bxy + c{y}^{2} + dx + ey + f = 0[/tex]

In this scenario, a is 1. c is 1 d is 4 and f is -6

Since a=c, we will get a circle.

Standard form of a circle is

[tex] (x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} [/tex]

where (h,k) is the center and r is the radius.

Step 1: Convert x^2+4x+y^2-6 into circle.

[tex] {x}^{2} + 4x + {y}^{2} - 6[/tex]

Add 6 to both sides

[tex] {x}^{2} + 4x + {y}^{2} = 6[/tex]

Complete the square with respect to x variable

Divide 4 by 2 and square it, then add that to both sides

[tex]( \frac{4}{2} ) {}^{2} = 4[/tex]

So add four to both sides

[tex] {x}^{2} + 4x + 4 + {y}^{2} = 6 + 4[/tex]

Remebrr that a perfect square is

[tex] {a}^{2} + 2ab + {b}^{2} = (a + b) {}^{2} [/tex]

So we get

[tex](x + 2) {}^{2} + {y}^{2} = 10[/tex]

That is our standard equation.

Look at the graph above.

Answer:

  a. -4/3

  b. -3(6x^2 +5)/(4(2x^3 +5x +4)^(7/4))

Step-by-step explanation:

The function can be evaluated at x = -1/2:

  (4(-1/2) -2)/(8(-1/2)^2 +1) = (-2 -2)/(8/4 +1) = -4/3

The limit at x = -1/2 is -4/3.

The power rule and chain rule will get you there:

  d(u^n) = nu^(n-1)·du

__

  g(x) = (2x^3 +5x +4)^(-3/4)

  g'(x) = (-3/4)(2x^3 +5x +4)^(-7/4)(6x^2 +5)

or ...

  g'(x) = -3(6x^2 +5)/(4(2x^3 +5x +4)^(7/4))

As per the two fractions above, Josephine actually painted:

Answer:

below.

Step-by-step explanation:

a.

1 block out of 4 blocks filled so she was supposed to fill

[tex]\frac{1}{4} [/tex] th of the painting or 25% of the painting.

b.

she only completed half of her assigned work so

[tex]\frac{1}{2} [/tex] fraction was done of her assigned portion. or 50% portion of the picture.

c.

[tex]\frac{1}{2}* \frac{1}{4} [/tex] = [tex]\frac{1}{8} [/tex]

Find the ratio between the two triangles by dividing two similar sides:

32/8 =4

The larger triangle is 4 times larger.

4x +12 = 15 x 4

4x +12 = 60

4x = 60-12

4x = 48

x = 48/4

x = 12

Answer: x = 12
