Answer:
12. (x, D, E, F) = (8, 38°, 75°, 67°)
13. (x, P, Q, R) = (13, 126°, 30°, 24°)
Step-by-step explanation:
The sum of angles in a triangle is 180°. We choose to write the equations assuming all measures are degrees.
12. (5x -2) +(9x +3) +(11x -21) = 180
25x = 200 . . . . . . . add 20, simplify
x = 8 . . . . . . . . . divide by 25
Then the angle measures are ...
∠D = 5(8) -2 = 38°
∠E = 9(8) +3 = 75°
∠F = 11(8) -21 = 67°
__
13. (10x -4) +(4x -22) +(x +11) = 180
15x = 195 . . . . . . . . . . add 15, simplify
x = 13 . . . . . . . . . divide by 15
Then the angle measures are ...
∠P = 10(13) -4 = 126°
∠Q = 4(13) -22 = 30°
∠R = 13 +11 = 24°

The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?
Answers
Answer:
5
Step-by-step explanation:
First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)
Answer:
4 nights
Step-by-step explanation:
148-40=108
108÷27=4
So, you spent 4 nights at the hotel.

Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms

Answers
Answer:
you would have to make 100s on at least 5 tests or assignments
Step-by-step explanation:
Answer:
It depends.
Step-by-step explanation:
Basically, your grade is a result of the average score on all of your assignments and even attendance. Average is all scores added together, divided by the number of scores. Also, depending on the teacher, some scores weigh more, meaning a test counts for more than a worksheet does.
Also, even if you get a 100 on your test, you'll unlikely get a 90. :(

f\left(n\right)=3f\left(n-1\right),\ n1=2

Answers
9514 1404 393
Answer:
[tex]\text{c. }f(n)=3f(n-1);f(1)=2[/tex]
Step-by-step explanation:
The first term is 2, so part of the recursive definition is ...
f(1) = 2
The common ratio is 6/2 = 3, so each term is 3 times the previous one. That part of the recursive definition is ...
f(n) = 3·f(n -1)
These two parts of the definition match choice C.
