Answer:
Answer is F
Step-by-step explanation:
How is elementary? just wondering haha seems hard for a kid
<span>Multiply the second equation by −4 to get −16x − 4y = −80 and </span>Multiply the first equation by 2 to get 4x + 8y = 28 both creates <span>an equivalent system such that, when combined with the other equation, one of the variables is eliminated</span>
Before it charged, the battery was at 23%. In half and hour, it went to 89%. So, it rose 89-23, or 66% in half an hour. Now that we know how much it rose and that there are 30 mins in half an hour, we have to divide 66% by 30 to figure out the answer.
66/30 is 2.2.
So, the battery rose at 2.2% per minute.
Hope this helps!
