Answer:
600
Step-by-step explanation:
Let's consider this question using algebra.
Imagine the number of bricks in the original pile is .
We are told that of the bricks are used for a project, meaning that
has been used, leaving us with
as our remainder.
Then, we are told that of the remainder are used to leave us with 50 bricks. This means that
of the remainder is left, and this is equal to 50 bricks. This means that the remainder's original amount is equal to 150, because we are told that
of the remainder is equal to 50.
So, we know that the remainder is 150, and we also know that the remainder is . Let's now use these to form an equation.
Because we know that a quarter of the original amount of bricks is equal to 150, we can multiply both sides of the equation by 4 to get the original amount of bricks in the pile.
So, there were 600 bricks in the original pile.
Answer:
Remember the property:
a^-1 = (1/a)^1
and:
(a/b)^n = (a^n)/(b^n)
A table for a function like:
Is just completed as:
So, here we have:
y = f(x) = (1/6)^x
To complete the table, we need to find:
f(-1)
and
f(2)
So let's find these two values:
f(-1) = (1/6)^-1 = (6/1)^1 = 6
and the other value is:
f(2) = (1/6)^2 = 1/36
Then the complete table is:
