2x - 1 + 3x = 0
2x + 3x - 1 = 0
(2 + 3)x - 1 = 0
5x - 1 = 0
Answer:
it took him 44 Minutes
Step-by-step explanation:
I would do linear combinations
if we simplify all of them by dividing the 2nd equation by -2 and the 3rd by 3, we get
x+y+2z=5
x+y+2z=5
x+y+2z=5
which is all the same plane, so there are infnitely many solutions
<span>To begin, there are only two ways to find die values beginning with a 3 that will give a score of greater than 14: (5,6). Moving to a first roll of 4, there are 3 values that will do the same: (4,5,6). A first score of 5 gives four values (3,4,5,6), and a first roll of 6 will give four values, as well (3,4,5,6). This gives a total of 13 out of 36 possibilities that will have a product of greater than 14.</span>
