Answer:
Step-by-step explanation:
4(x-3)2-5 = 139
(4x-12)-5=139
-20x + 60 = 139
-20x +60 - (60) = 139- 60
-20x = 79 divide both sides by -20
x = -3.95

11.84 rounded to the nearest whole number is 12. It’s simple add all c,d, and f percents. Then turn the percent into a decimal by dividing by 100, and multiply that decimal by the students , which is 32.
The airplane is 100 feet long because 5*4=20 so
that would mean that 20*5=100
Answer:
AM = 38
Step-by-step explanation:
Since A is the midpoint of JM, then
JA = AM = 6x - 4 , and
JA + AM = JM ← substitute values
6x - 4 + 6x - 4 = 9x + 13, that is
12x - 8 = 9x + 13 ( subtract 9x from both sides )
3x - 8 = 13 ( add 8 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Hence
AM = 6x - 4 = (6 × 7) - 4 = 42 - 4 = 38
