Answer:
D
Step-by-step explanation:
(-1) + (-1) = -2... so 500 times... it would be -500.
B.66 I am positively absolutely sure. Hope this helps!
Answer:
here's what we know:
a + b = 72
a - b = 26
We can use the elimination method to solve this problem:
a + b = 72
a - b = 26
---------------
2a = 98
Divide both sides by 2:
a = 49
So we now have:
49 + b = 72
and:
49 - b = 26
Subtract 49 from both sides:
b = 23
and
-b = -23 (multiply both sides by -1) → b = 23
Step-by-step explanation:
400x=22,000
22,000/400=x
55=x Hopefully this is right, and hopefully this helps
