employed: 1,312,700 people
- employed : 100% - 5.6% = 94.4%
employed people:
4x -3y + z = -10...............(1)
2x +y + 3z = 0...............(2)
-x +2y - 5z = 17...............(3)
First we multiply 3*(2) and add it to (1)
6x +3y +9z =0..................+(1)..................> 10x + 10z = -10......(4)
Then we multiply -2*(2) and add it to (3)
-4x -2y -6z =0 ...................+(3)................> -5x -11z = 17...........(5)
Multiply 2*(5) and add it to (4)
-10x -22z = 34...................+(4).................> -12 z = 24 ..............>>> z = -2
Substitute z in (4)............> 10x +10(-2) = -10.............................>>> x = 1
Substitute x and z in (2).....> 2(1) +y + 3(-2) = 0..................>>> y = 4
Solution (x,y,z) = (1,4,-2)
"A student" doesn't register for 46,140 credits, unless he wants to be very very busy.
If ALL of the students on campus register for 46,140 credits, then many colleges
would estimate the number of full-time students by using the formula
f = n / 15 = 46,140 / 15 = <u>3,076</u> students.
That's not the formula for 'n'. 'n' is the total number of credits for the semester,
and the question tells you what 'n' is. Knowing 'n', the formula helps you find 'f'.
37 is the correct answer givenbthat 12 and 35 are the original baces but if not then the hypotenuse is 6.08
F + 0.3 < 1.7
Subtract 0.3 on both sides
F < 1.4
Your final answer is F < 1.4
