Answer: 41.833333
Step-by-step explanation:
2x + 3y = 12 (1st)
5x − y = 13 (2nd) ---> y = 5x - 13
Substitute y = 5x - 13 into (1st) equation
2x + 3(5x - 13) = 12
2x + 15x - 39 = 12
17x - 39 = 12
17x = 51
x = 3
substitute x = 7 into y = 5x - 13
y = 5x - 13
y = 5(3) - 13
y = 15 - 13
y = 2
Answer
solution x = 3 and y = 2
Answer:
total number of possible outcome is 36
Step-by-step explanation:
if the two dice are thrown simultaneously and we set out the possible combinations;
for example,
(1,1) (1,2), (1,3) (1,4) (1,5) (1,6), (2,1) (2,2) (2,3) .... in that order, we will discover that the most probable even is an outcome of 36
