Answer:
Total no.of possible outcomes = 200 × 4 = 800
No.of favourable outcomes = 200 × 1 = 200
P (E) = no.of favourable outcomes / total no.of possible outcomes
= 200/800
= 1/4
Answer: Planning because you need to start somewhere if you dont then you dont have any of the other steps
Good luck lovie :)
Answer:
y=-5,x=2
Step-by-step explanation:
3x+3y=-9________________eqn 1
3x-3y=21________________eqn 2
using elimination method
3x+3y=-9
-
3x-3y=21
subtract equation 2 from equation 1
0+6y=-30
6y=-30
y=-30/6
y=-5
substitute the value of y in equation 1
3x+3y=-9
3x+3(-5)=-9
3x-15=-9
3x=-9+15
3x=6
x=6/3
x=2
