Answer:

90+30=120

180-120=60 this is degree measure

Step-by-step explanation:

(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)

Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.

We know that (n - 2) + n + (n + 2) = 78,

so 3n = 78, and n = 78/3 = 26.

Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Hey there!

[tex]Answer:\boxed{x=\frac{-1}{2}y+17}\boxed{y=-2x+34}[/tex]

[tex]Explanation:[/tex]

[tex]y=-2x+34[/tex]

flip the equation.

[tex]-2x+34=y[/tex]  flip the equation.

Now add -34 to both sides of the equation.

[tex]-2x+34+-34=y+-34\\-2x=y-34[/tex] add -34 to both sides of the equation.

In our third/last step, we will divide both sides of the equation by -2.

[tex]\frac{-2x}{-2}=\frac{y-34}{-2}[/tex] divide both sides of the equation by -2.

[tex]x=\frac{-1}{2}y+17[/tex] The answer to your equation.

There is nothing to solve for y because the equation was equal to y.

Hope this helps!

Answer:

Erin should stop at three and a half rounds.

Step-by-step explanation:

One complete round will mow 954 square feet, the total area that she has to mow 3375 square feet. If she goes around three and a half times, she should be finished and stop. This was quite hard to figure out, and may very well be incorrect in some way, but I hope this helps.

Answer:

x = -3

Step-by-step explanation:

First, distribute:

-2x - 16 = 6x + 8

Then, switch the numbers to one side, and switch the variables to another:

-2x - 6x = 8 + 16

Then, simplify:

-8x = 24

Finally, divide -8 on both sides:

We got x = -3

And we're done!

Answer:

24a³

Step-by-step explanation:

Simplify, then,  2.1  2³ divided by 2¹= 2 (³_¹)= 2²

( 3 . 4³ .2.   =24a³.

Simplification of an expression is making it as simple as possible. The simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

If we have [tex]a^b[/tex] then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}\\\\^n\sqrt{a} = a^{1/n}\\(ab)^c = a^c \times b^c[/tex]

For the given case, the expression is simplified by using the given rules as:

[tex][3(2a)^{3/2}]^2 = 3^2 \times (2a)^{\dfrac{3}{2} \times 2} = 9 \times (2a)^3\\[/tex]

[tex][3(2a)^{3/2}]^2 = 9 \times 8 \times a^3 = 72a^3[/tex]

Thus, the simplified form of the considered expression is given by: Option D: [tex]72a^3[/tex]

Answer:

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

F (5,5) , G (−3,−1)

The distance between them is

[tex] |FG| = \sqrt{( {5 + 3})^{2} + ({5 + 1})^{2} } \\ = \sqrt{ {8}^{2} + {6}^{2} } \\ = \sqrt{64 + 36} \\ = \sqrt{100} \: \: \: \: \: \: \: \: \\ = 10 \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

Hope this helps you

Distance formula: d = √(x2-x1)²+(y2-y1)²

= √(x2-x1)²+(y2-y1)²

= √(-3-5)²+(-1-5)²

= √-8²+(-6)²

= √64+36

= √100

= 10

Answer:

The triangle is isosceles.

Step-by-step explanation:

WHY?:

An Isosceles Triangle will have both 2 equal sides and 2 equal angles.

A Equilateral Triangle will have 3 equal sides and 3 equal angles.

A Scalene angle is when all 3 sides have different lengths.

and

A right triangle will have a 90 degree angle.

In triangle LMN, LM is perpendicular on side MN. So that, the triangle LMN is right angle triangle.

To understand more, check below explanation.

A triangle whose all three sides has different length known as scalene triangle.

A triangle in which all three sides are equal in length known as equilateral triangle.

A triangle in which two sides are equal are known as isosceles triangle.

A triangle in which one angle is 90 degrees known as right angle triangle.

Since, In traingle LMN, LM is perpendicular on MN. Therefore, LMN is right angle triangle.

scale factor = 2.5

x = 10

Step-by-step explanation:

to find the scale factor, divide 10 by 4.

use the answer and divide it by 25 :)

________

10÷4=2.5

25÷2.5=10

The scale factor is 2.5 and the value of x will be 10.

The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. The scale factor is the ratio of the scaled size to the original size.

Given that one triangle has the sides x and 4 and another has 25 and 10.

The scale factor will be calculated as below:-

Scale factor = 10 / 4

Scale factor = 2.5

Use the answer and divide it by 25. The value of x will be calculated as below:-

x = 25÷2.5

Answer:

Positive

Step-by-step explanation:

[tex]\frac{2}{5}-(-\frac{5}{6})[/tex]

Remember, a number minus the negative of a number would be equal to that first number plus that second number but not negative. In other words:

a - (-b) = a + b

So:

[tex]\frac{2}{5}-(-\frac{5}{6})=\frac{2}{5}+\frac{5}{6}[/tex]

The sum of two positive numbers would be a positive number. Because of this, we can see that the value would be positive.
