Generate a plan and describe the steps needed to solve the equation. 34=-(m+3)

2 answers:

6 1

Alright to solve this problem you must start by distributing the -1 to everything in the parenthesis. To distribute, multiply both the m variable and the 3 by a -1.
This simplification results in:
34 = -m - 3

Next, isolate your -m. To do this, add 3 on both sides of the equal sigh to keep everything balanced.
This gives you:
37 = -m

Since you want to find the value of m and not -m, flip the sign of the value in your answer by moving the negative parenthesis to the integer rather than the variable.
Like this: -(37) = m

Then, distribute the negative to your integer value.
Your simplified equation now looks like this:
-37 = m

This leaves your final answer value for m as a -37.

I hope this is correct and helpful to you! :)

Answer:

Sample response: The negative sign outside the parentheses represents –1. Distribute the –1 to everything inside the parenthesis. Use the addition property of equality first to add 3 to both sides. Then use the division property of equality to divide both sides by -1.

After learning the midpoint construction Sally realizes that she could determine one fourth the length of a segment how could sh

Viefleur [7K]

The midpoint of two points is the point which divides the line segment joining the two points into two equal parts.

Suppose, we have a line segment AB with a point C, between point A and point B such that the distance AC is equal to the distance CB, then we say that point C is the midpoint of line AB.

Suppose, we have another point D between point A and point C, such that the distance AD is equal to the distance DC, then we say that point D is the midpoint of AC.

Notice that point D is a fourth of line segment AB.

Thus, AD is <span>one fourth the length of segment AB.

Therefore, one fourth the length of a segment can be obtained by evaluating the midpoint of the midpoint of the line segment.

Ainsley lives in a town 360 miles directly north of Orlando, and one Saturday, she takes the train from her town to the city. he

iragen [17]

By definition we have to:
d = v * t
where,
d: distance
v: speed
t: time
We have then that the speed is:
(360-210) = v * 2.5
Clearing we have:
v = (360-210) /2.5
v = 60 mph
We now write the generic equation of distance:
d (x) = 60x
Where,
x: time
Answer:
an equation that represents (x), the distance Ainsley is from Orlando after x hours is:
d (x) = 60x

Regular hexagon ABCDEF has a perimeter of 36. O is the center of the hexagon and of circle O. Circles A, B, C, D, E, and F have

morpeh [17]

Answer:

E. (54\sqrt{3}-27\pi\)

Step-by-step explanation:

I draw the figure described by the statement down there so you can see easily how to solve it.

Notice 3 things:

- The length of one side of the hexagon is simply 36 divided by 6. = 6 This is beacause, by nature, every single side of the hexagon has the same length.

- The radius of each circle is half the length of one side of the hexagon. This would mean that the radius of each circle is 3.

- The outer circles have 120°/360° of its area enclose. We get this value because by definition, the hexagon can be divided into 6 regular triangles, each one with every angle equal to 60°. The size of the internal angles of the hexagon will be twice this value.

So, in summary, The area enclosed by the circles is expressed like this:

Acircles = 6 * $\frac{120}{360}$ * π * (r)² + π*r² = 3 * π * r² = 27 π

Now all we need is the area of the regular hexagon, which is simply:

Ahexagon = $\frac{1}{2}$ * p * a

Where p is the perimeter, given by the problem, and a is its apothem, the distance between the center of the hexagon and the middle of one of its sides, that is found by multiplying the length of a side of the hexagon times $\frac{\sqrt{3}}{2}$ .

Ahexagon = $\frac{1}{2}$ * 36 * 6 * $\frac{\sqrt{3}}{2}$ = 54 $\sqrt{3}$ .

Then, the area of the shaded area is equal to:

Ashaded = Ahexagon - Acircles = 54 $\sqrt{3}$ - 27π
