Answer:
n = -3
Step-by-step explanation:
-5n -3(n+2) = 18
-5n - 3n - 6 = 18
-8n - 6 = 18
-8n = 18 + 6
-8n = 24
n = -3

Answer:
Alternate Interior angles! ? = 50 :)
Step-by-step explanation:
They are both interior, and they are alternate, so the type of angle pair is an alternate interior angles pair!
Relationship: They are congruent to each other!
They are also both equal! :)

Consider the line y=-4x+8.
Find the equation of the line that is parallel to this line and passes through the point (5, 4).
Find the equation of the line that is perpendicular to this line and passes through the point (5, 4).
Answer:
parallel------> y = - 4x + 24
perp.---------> y = 1/4x - 3/2
Step-by-step explanation:
parallel: 4 = - 4(5)+ b
4 = -20 + b
+20 = +20 + b
24 = b
y = -4x + 24
perpendicular: 4 = 1/4(5) + b
4 = 5/4 + b
- 5/4 = - 5/4 + b
- 3/2 = b
y = 1/4x - 3/2

7. -5a + 7 = -38
Please show your work
Answer:
[tex]\boxed{\tt a=9}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]-5a+7= -38[/tex]
We want to solve for a, so we must isolate a on one side of the equation.
7 is being added to -5a. The inverse of addition is subtraction. Subtract 7 from both sides of the equation.
[tex]-5a+7-7=-38-7[/tex]
[tex]-5a=-38-7[/tex]
[tex]-5a=-45[/tex]
a is being multiplied by -5. The inverse of multiplication is division. Divide both sides of the equation by -5.
[tex]\frac{-5a}{-5} =\frac{-45}{-5}[/tex]
[tex]a=\frac{-45}{-5}[/tex]
[tex]a=9[/tex]
Let's check our solution. Plug 9 in for a.
[tex]-5a+7=-38[/tex]
[tex]-5(9)+7=-38[/tex]
[tex]-45+7=-38[/tex]
[tex]-38=-38[/tex]
This checks out, so we know our solution a=9 is correct.
-5a +7 =-38
-5a +7 (-7) = -38 (-7)
-5a= -45
-5a (÷-5)= -45 (÷-5)
a= 9

Prove that angles opposite to equal sides of an isosceles triangle are equal.
Answer:
Step-by-step explanation:
Take a triangle ABC, in which AB=AC.
Construct AP bisector of angle A meeting BC at P.
In ∆ABP and ∆ACP
AP=AP[common]
AB=AC[given]
angle BAP=angle CAP[by construction]
Therefore, ∆ABP congurent ∆ACP[S.A.S]
This implies, angle ABP=angleACP[C.P.C.T]

Two radio stations are playing this week's #1 hit song. One radio station plays the song every 18 minutes. The other radio station plays the song every 24 minutes. Both stations play the song at 3:00 P.M. When is the next time the stations will play the song at the same time?
3:18 PM
Answer:
The will play the song at the same time by 4:12 pm
Step-by-step explanation:
here, we want to know the time both radio station will play the song after 3pm.
Mathematically to get this, we shall need to find the lcm of both 18 and 24. LCM stands for the lowest common multiple of both.
The lowest common multiple of both is 72.
This means that after 72 minutes, they will both play the song
So the time then would be;
72 + 3 = 4 : 12 pm
Find the MAD: 36,42,41,32,30
Answer:
4.24
Step-by-step explanation:
Answer:
144.8 would be your answer, if I'm not mistaken.
Step-by-step explanation:
To find the MAD (Mean Absolute Deviation) you have to add up all the numbers and divide it by the amount of numbers you are being given:
[tex]36+42+41+32+30=181[/tex]
Then divide it by 5 because we added 5 numbers together:
[tex]\frac{181}{5} =36.2[/tex]
People actually do it like this:
[tex]\frac{36+42+41+32+30}{5} = 181[/tex]
(Which is the same thing, except it's faster, in my opinion)
Well, now that we have the sum (181) we have to subtract it from all those numbers we were given:
[tex]181-36=145, 181-42=139, 181-41=140, 181-32=149, 181-30=151.[/tex]
Now add up all those numbers together and divide it by 5 again:
[tex]\frac{145+139+140+149+151}{5} =144.8[/tex]
