Answer:
-40
Step-by-step explanation:
Let's input x into all of the slots.
Now, let's solve!
So, the answer is -40!
Given that the formula we are required to solve for h:
a=4b^5h
to solve for h we divide both sides by 4, this will give us:
a/4=(4b^5h)/4
a/4=b^5h
next we divide both sides by b^5, this will give us:
a/(4×b^5)=(b^5h)/b^5
a/(4b^5)=h
hence the answer is:
h=a/(4b^5)
After guessing and checking, the answer is around 68.8. You can use this problem to find the answer in much more reliable ways as well.
He gets an average between 80 and 90
It is between these two values
So it could be 80 or higher but it must be 90 or belowe so it can be equal to 80 or above and it can be equal to 90 or below
This gives two inequalities 80 ≤ x and x ≤ 90
This can be written as 1 inequality 80 ≤ x ≤ 90
≤ this means less than or equal to the one that points the opposite way would be greater than or equal to think of it as a number line pointing right is positive meaning the numbers get bigger, getting greater pointing left is getting smaller so it gets less and less
