Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
x+y=-4
3x-6y=15
---------------
x=-4-y
3(-4-y)-6y=15
-12-3y-6y=15
-12-9y=15
9y=-12-15
9y=-27
y=-27/9
y=-3
x+(-3)=-4
x-3=-4
x=-4+3
x=-1
Answer:

100% - 62% = 38% walking to school
Answer:
11. ∠B ∠ABC ∠CBA ∠2
17. QR = 12
Step-by-step explanation:
11. ∠B ∠ABC ∠CBA ∠2
17. Given: PS = 18 PR = 15 PQ ≅ RS
It would be good if you could draw a picture for yourself
So, RS = PS - PR
= 18 - 15 = 3
RS = PQ = 3
QR = PS - RS - PQ
= 18 - 3 - 3
= 12
