Step-by-step explanation:
here's the solution: -
Average time taken by sarah :
=》
=》
=》
average time taken by sarah = 70.9 seconds
now,
average time taken by katie :
=》
=》
=》
average time taken by katie = 78.9 seconds
so, sarah is more efficient (faster) than katie.
i agree with sarah.
cuz, she took less time than katie.
Answer: The car's maximum speed
have a nice day!!
That is easy!! :)
y=3 and x=-7
When you find the factors of something like this, you have to just get the letter alone.
For example: y-3. You have to first write it as y-3=0, then you add 3 from BOTH sides of the = so that you can make the -3 go away and y will be alone. So, it will look like this: y-3+3=0+3. Then, you solve it for y (which just means that you want y by itself on one side of the = ). So, -3+3=0, which means they disappear from that side; since 0+3=3, that's what that side turns into, so what you end up with is y=3
Same thing goes for the x+7 equation:
x+7=0
x+7-7=0-7
x=-7
I believe 64x-8 is the correct answer.
