Answer:
All numbers 0+
Step-by-step explanation:
1-1=0
2-2=0
3-3=0
And so on. Any number 0 and up minus itself= 0.
10x10x10x10x10x10 That will eb your answer in exponential form.
The number line is a bit hard to read but from the numbers and looks from it, it looks correct
X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
