12x+15y=34 and -6x+5y=3

pls like and follow my page thank you

Step-by-step explanation:

using elimination method...you will have it as

12x+15y =34 1

-6x+5y = 3 2

multiply equation 1 by 6 and equation 2 by 12

72x + 90y = 2044

-72x + 60y = 365

asd equation 2 and 1...

0x + 150y = 240

y= 240/250 ..

after getting your answer ..

substitute for y in either of equation 1 and 2 to get your x

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
