Answer:
Step-by-step explanation:
The following ratio solves the problem
AM/MN = x / MP
(67.2 - 32) /67.2 = x / 81.9
35.2 / 67.2 = x / 81.9
Cross Multiply
67.2 * x = 81.9 * 35.2
67.2 x = 2882.88
Divide by 67.2
x = 2882.88 / 67.2
x = 42.9
Answer:
360
Step-by-step explanation:
6C4 × 4! = 360
For this case we have the following system of equations:
We must solve the system by the method of elimination. To do this we multiply the second equation by -3, then:
We add both equations:
We find the value of "x":
Thus, the solution of the system is:
We verify:
