Answer:
(0,3)
Step-by-step explanation:
7x-2y=-6
8x+y=3
Multiply the second equation by 2 so we can eliminate y
2(8x+2y) = 2*3
16x+2y=6
Add the first equation to the modified second equation
7x-2y=-6
16x+2y=6
--------------------
23x = 0
Divide by 23
23x/23 = 0/23
x =0
Now we need to find y
8x+y = 3
0+y =3
y=3

Answer:
John read for 3 hours
Step-by-step explanation:
j = 0.5t; t = 0.5s; s = 2m; m = 6
s=2(6), s=12; t=0.5(12), t=6; j=0.5(6), j=3
Answer:
Step-by-step explanation:
total students = 27
students do not have a brother probability = 13/27
students do not have a sister probability = 12/27
= 4/9
Hope this is correct :)
