Answer:
(x,y)=-(1,1)
Step-by-step explanation:
-2x=8-6y (divide by -2)
=> x=-4+3y
-15x=21-6y (divide by -3 for simplicity)
=>5x=-7+2y
We know that x=-4+3y, insert this into expression "5x=-7+2y"
5(-4+3y)=-7+2y
-20+15y=-7+2y
15y-2y=20-7
13y=13
y=1
Since x=-4+3y we can find x by using y=-1
x=-4+3(1)
x=-1
The answer would be 15000, be cause it is more than half a thousand so it would round up a thousand making it 15 thousand.<span />
Answer:
(E) 9
Step-by-step explanation:
A= 4
B= 5
C= 0
a+b+c= 4+5+0= 9
a+b=9= 4+5=9
a+c=4= 4+0=4
b+c=5= 5+0= 5
