This is the concept of algebra, so solve for x we proceed as follows;
4/x-4=x/(x-4)-4/3x
(4-4x)/x=(3x^2-4(x-4))/(3x(x-4))
(4-4x)/x=(3x^2-4x+16)/(3x^2-12x)
cross-multiplying the expression we get:
(4-4x)(3x^2-12x)=x(3x^2-4x+16)
-12x^3+60x^2-48x=3x^3-4x^2+16x
this can be simplified as:
-15x^3+64x^2-64x=0
since the above polynomial is of degree 3, the number of solutions are 3.
Wait is that x to the power of two???
Let
x---------> the number
we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6
the answer is
-6
Answer:
60 mins or 1 hour
Step-by-step explanation:
14 x 2 : 28 - 25 plus 25 is 50 min
38- 28 is 10
50 plus 10 is 60 min Or 1 hour
Answer:
The data is missing, However the answer is given below
Step-by-step explanation:
The data is missing about the runners and the duration minutes taken to complete the race, However the answer is given below
(3 * 4) + (8 * 3)
12 + 24
36 silver medals would have been awarded to runners.
The data is missing for the runners of the race and the time they took to complete the race, silver medal is awarded for runners who completed race in 37 to 38 minutes.
