Answer: -12
Step-by-step explanation: To solve this problem, we can first start by rewriting the problem. When we add a negative, that's exactly the same thing as subtracting so we can make the problem easier to understand.
18 + (-30) → 18 - 30
To find the answer to this problem, let's first find out how many jumps it get's to 0 from 18. It would take 18 jumps and there is 12 jumps left over. Then, we would subtract 12 from 0 and we would get -12 as our answer. Therefore, 18 + (-30) = -12.
Answer:
the equation does not make sense
Answer:
I believe it is -6
Step-by-step explanation:
2x + 1 = 5
Subtract 1 from each side:
2x = 4
Divide each side by 2 :
x = 2 .
That's the solution to your equation.
It's exact, and doesn't need any rounding.
