Answer: 40/2=3
Step-by-step explanation:
Answer:
392000
Step-by-step explanation:
8*10^4 = 80000
4*10^6= 4000000
4000000 - 80000 = 392000
Answer : number 4 is a dependent system
Explanation:
If we look at number 4
2x+2y=6 , y= -x+3
2(x+y)=6
x+y=6/2=3
y=-x+3
Now we see that the two equation have the same slope (-x) and the same y intercept (+3) we can clearly say that these 2 equation are dependent because it has infinite solution
Answer:
ok I really suck at math, but I think you may have to multiply the x/y to get the whole area of the circle. so maybe itd be 10x25. I'm sorry if this isnt correct
