Answer: B) Michiko is right for this system of linear equations, and her method will also work for other systems of linear equations

Hope this helped

Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

Two or more expressions with an Equal sign is called as Equation.

To solve the system of linear equations 15x + 8y = 1 and 21x + 4y = -13, Michiko suggests multiplying the second equation by 2 and then subtracting the second equation from the first equation.

Multiplying the second equation by 2 gives:

42x + 8y = -26

Now, subtracting the second equation from the first equation gives:

15x + 8y - (42x + 8y) = 1 - (-26)

Simplifying this equation gives:

-27x = 27

Divide both sides by 27

x=-1

we can substitute x = -1 into either of the original equations.

Using the first equation, we get:

15(-1) + 8y = 1

Simplifying this equation gives:

8y = 16

Dividing both sides by 8 gives:

y = 2

Hence, Michiko is right for this system of linear equations, but her method will not work for other systems of linear equations, option A is correct.

Answer:

2. Surface Area = 576m^2

3. Surface Area = 300 yd^2

Step-by-step explanation:

2.

Surface Area of Prism Formula:

Triangle Formula: Area = 1/2 * Base * Height

Left Triangle: Area = 1/2 * 8m * 6m = 1/2 * 48 = 24 m^2

Right Triangle:  Area = 24m^2

Rectangle Formula: Area = Length * Width

Top Rectangle: Area = 22m * 6m = 132m^2

Middle Rectangle: Area = 22m * 8m = 176m^2

Bottom Rectangle: Area = 22m * 10m = 220m^2

Add Total Surface Area:

Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect

Surface Area = 24  + 24 + 132 + 176 + 220

Surface Area = 576 m^2

3.

Surface Area of Prism Formula:

Triangle Formula: Area = 1/2 * Base * Height

Left Triangle: Area = 1/2 * 9yd * 4yd = 1/2 * 36 = 18 yd^2

Right Triangle:  Area = 18 ydm^2

Rectangle Formula: Area = Length * Width

Top Rectangle: Area = 12yd * 8yd = 96yd^2

Middle Rectangle: Area = 12yd * 5yd = 60yd^2

Bottom Rectangle: Area = 12yd * 9yd = 108yd^2

Add Total Surface Area:

Surface Area = LTrig + RTrig + TopRect + MidRect + BotRect

Surface Area = 18 + 18 + 96 + 60 + 108

Surface Area = 300 yd^2

Step-by-step explanation: pls friend can i get branliest and thanks

My goodness, this is rather confusing in the way it is worded. Nevertheless, I will attempt to do what I can. Just please keep in mind that this is my own interpretation of the problem, and therefore could be... incorrect.

I think, to start out, we could set up the problem like so

15 + t ≥ 26

because t is not a set number.

Then all that is needed is to subtract 15 from both sides, and the equation becomes

t ≥ 11

So the resulting answer is t ≥ 11.

I hope that my interpretation helps.

Step-by-step explanation:

Absolute value bars ask for the distance of a number and 0 so |-8| is equal to 8 since it is 8 units away from zero, |7| would be equal to 7 since it is 7 units away from 0. To do the more complicated problems simplify the equation as much as possible and then solve.

Answer:

x = 37°

x = 40°

x = 260°

Step-by-step explanation:

To find angle x when two secants or tangents intersect outside the circle, simply subtract the smaller arc from the bigger arc and half the result.

Question 1

[tex]x=\dfrac12(128^{\circ}-54^{\circ})=37^{\circ}[/tex]

Question 2

To find the bigger arc, subtract the smaller arc from 360°

⇒ 360° - 140° = 220°

[tex]x=\dfrac12(220^{\circ}-140^{\circ})=40^{\circ}[/tex]

Question 3

The smaller arc can also be found by subtracting the external angle from 180°

Smaller arc = 180° - 80° = 100°

[tex]80^{\circ}=\dfrac12(x-100^{\circ})[/tex]

[tex]160^{\circ}=x-100^{\circ}[/tex]

[tex]x=260^{\circ}[/tex]

#1

#2

Bigger Arc=360-140=220°

#3

Smaller arc=180-80=100°

Range = 7

Mean = 7.75

Assumption: Most students will have 7 or 10 letters in their last name

Step-by-step explanation:

Range = Largest - Smallest

           = 10 - 3

           = 7

Mean = Add the total numbers up to get a total / numbers in the series

          = (3+5+2(6)+2(9)+5(7)+4(8)+5(10)) / (1+1+2+5+4+2+5)

PRQ was translated 90 degrees clockwise.

If (6,-54) is located in q4 (+,-) and rotated to land on (-6,-54) which is in q3 then it was rotated 90 degrees clockwise.

Step-by-step explanation:

Answer:

Let u = √x which gives u2= x and rewrite the given equation in terms of u

u = 3 - u 2 / 4

Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.

u 2 + 4 u - 12 = 0

Two solutions: u = - 6 and u = 2

Use the substitution used above u = √x to solve for x.

u = - 6 = √x has no solution

u = 2 = √x has solution x = 4

Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.

Step-by-step explanation:

Answer: x = 4

Step-by-step explanation:

    Given:

√x = 3 - (1 / 4)x

    Rewrite:

[tex]\displaystyle \sqrt{x} = 3 - \frac{1}{4}x[/tex]

    Square both sides:

[tex]\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}[/tex]

[tex]\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9[/tex]

    Set the equation equal to 0:

[tex]\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0[/tex]

    Use the quadratic formula:

[tex]\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}[/tex]

x = 4, 36

    Plugging back into equation shows us only one answer works,

x = 4

C. 1/5 divide by 4

Step-by-step explanation:

When you divide two fractions, you multiply the first fraction by the reciprocal of the other one. To find the reciprocal of the second fraction, yo just have to switch the value of the numerator and denominator (i.e. 4/1's reciprocal is 1/4).

Another important thing to note is that 1/5 x 1/4 is 1/20 because you multiply straight across numerators and denominators.

Now that we have some back ground information, let's which expression leads to 1/20!

A:

B:

Answer:

about 101 miles to equal the same amount as place A. (if this is daily")

Step-by-step explanation:

so how I went about this is first I added 55+0.33 because thats how much you need to drive one mile for one day with place A. and that equaled 50.30 so then I divided 50.30 by 0.55 because thats all it costs per mile for place B so I got 100.545454545 so i just rounded it up to 101
