Algebraically:
13 + (38/60) + (35/3600) = 13. 6431 degrees
If you have a graphing calculator ( I am using a TI-84 plus Silver Edition):
13(press 2nd -> apps -> 1) 38 (press 2nd -> apps -> 2) 35 (press alpha -> +) = 13.6431
3 pen + 2 pencil = .47
2 pen + 3 pencil = .38
2(3pen + 2 pencil = .47)
-3(2pen + 3 pencil = .38)
6 pen + 4 pencil = .94
-6 pen - 9 pencil = -1.14
- 5 pencil = -.2
pencil = .04
3pen + 2(.04) = .47
3pen + .08 = .47
3 pen + .08 - .08 = .47 -.08
3 pen = .39
pen = .13
Pen = 13 cents and pencil = 4 cents
Answer: X = -12
Step-by-step explanation: 1) 12 + x/4 = 9
2) 12 + x/ 2^2 = 9
3) x/ 2^2 + 12 = 9
Answer:
Step-by-step explanation:
The layout looks like this.
r-----------s-----------------t
6.4
----------------9.3-----------
Now you want st so the formula is
rt = rs + st
9.3 = 6.4 + st Subtract 6.4 from both sides
9.3 - 6.4 = st Combine
st = 2.9
