Answer:

21x-1=19x+11(by alternate exterior angle)

21x-19x=11+1

2x=12

X=12/2

X=6

Answer:

Angle B is 120°

Step-by-step explanation:

Since it's a supplementary angle (angles that add up to 180°) on top of the triangle, you would find ∠B by subtracting 180 by 60 and ∠B will be 120°. Hope this helps:)

Answer:

To find a range of values for the third side when given two lengths, write two inequalities: one inequality that assumes the larger value given is the longest side in the triangle and one inequality that assumes that the third side is the longest side in the triangle. Combine the two inequalities for the final answer.

Step-by-step explanation:

Answer:

To find a range of values for the third side when given two lengths, write two inequalities: one inequality that assumes the larger value given is the longest side in the triangle and one inequality that assumes that the third side is the longest side in the triangle. Combine the two inequalities for the final answer.

Step-by-step explanation:

ex: a triangle has side lengths 3, and 7, find the possible range length for the third side.

Solution: let x be the length of the third side of the triangle

The maximum value:

x<3+7=10                            ______ x<10

The mimimum value:

x>7-3=4                          ________ x>4

so 4<x<10  ( x is between 4 and 10)

Hope that made sense and helped!

Answer:

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

Answer:

A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers. We have a top number, the numerator, and a bottom number, the denominator. For example, 1/2 is a fraction.

Answer:

-1, -7, -13, -19

Step-by-step explanation:

-2(-3)-7 =6-7= -1

-2(0)-7 =0-7= -7

-2(3)-7 =-6-7= -13

-2(6)-7 =-12-7= -19

Answer:

(-3,-1)(0,-7)(3,-13)(6,-19)

Step-by-step explanation:

Put the x number into the x in the equation to get your answer:

y=-2(-3)-7    y=-1

y=-2(0)-7     y=-7

y=-2(3)-7      y=-13

y=-2(6)-7     y=-19

Answer:

m=9

Step-by-step explanation:

3m-6-2m=3

Combine like terms

3m-2m=1m

1m-6=3

Add 6 to both sides

1m=9

Divide both sides by 1

m=9

Hi there! Your answer is m = 9

Please see the explanation for a clear understanding to the problem.

Any questions about the answer/explanation, feel free to ask in comments! :)

Step-by-step explanation:

Goal

Given

[tex]\Large{3m-6-2m=3}[/tex]

Step 1

Like terms are the terms have same variables. For example, 2m and 3m. 2m and 3m both are like terms because they both have same variable which is m-term.

But 2m and 3a are not like terms because 2m has m-term as a variable but 3a has a-term as a variable. Both are terms but not like terms.

From the equation:

[tex]3m-2m=3+6[/tex]

Since we combine like terms, we can't combine a constant with a variable so we move to the side where they are alike.

Evaulate 3m-2m = m and 3+6 = 9

[tex]m = 9[/tex]

There aren't really much steps solving this. The next step is going to be how to check an answer. It's useful when you are not certain or sure about the answer that you get. If you are not certain on the answer, this step is highly advised for a beginner.

Optional Steps - Answer Check

Step 2

The step is optional as said. From the equation:

[tex]3m-6-2m=3[/tex]

We can do this two ways which are when we simplify the equation then substitute in the value of m or we substitute m-value first then simplify/evaluate.

I will be demonstrating these two steps to you.

Step 2.1

[tex]3m-6-2m=3\\3m-2m=3+6\\m=9\\9=9[/tex]

Step 2.2

[tex]3m-6-2m=3[/tex]

Substitute m = 9 in the equation.

[tex]3(9)-6-2(9)=3\\27-6-18=3\\9-6=3\\3=3[/tex]

Notice that no matter which method you use, you'd still get the same answer. Since the equation is true for m = 9. Therefore, the solution is m = 9.

48=7x+13

step 1 subtract each side by 13

35=7x

step 2 divide each side by 7

x=5

Answer:

y=1/3x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-1)/(0-15)=-5/-15=1/3

y-y1=m(x-x1)

y-1=1/3(x-15)

y=1/3x-15/3+1

y=1/3x-5+1

y=1/3x-4

Step-by-step explanation:

Given

4a - 2b

= 4[tex]\left[\begin{array}{ccc}4\\7\\\end{array}\right][/tex] - 2[tex]\left[\begin{array}{ccc}2\\4\\\end{array}\right][/tex] ← multiply each component by the scalar

= [tex]\left[\begin{array}{ccc}4(4)\\4(7)\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}2(2)\\2(4)\\\end{array}\right][/tex]

= [tex]\left[\begin{array}{ccc}16\\28\\\end{array}\right][/tex] - [tex]\left[\begin{array}{ccc}4\\8\\\end{array}\right][/tex] ← subtract corresponding components

= [tex]\left[\begin{array}{ccc}16-4\\28-8\\\end{array}\right][/tex]

= [tex]\left[\begin{array}{ccc}12\\20\\\end{array}\right][/tex] = [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]

with x = 12 and y = 20
