Answer:
The difference of 8 times a number r and 12 is solved for a number r and is given by
Step-by-step explanation:
Given problem is the difference of 8 times a number r and 12
It can be written as
To simplify the above expression :
8r-12
( using addition property of equality )
(using division property of equality )
Therefore
Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by
Answer:
6 games
Step-by-step explanation:
if one lady had 3 pieces of candy, that means she must have gotten them from the other lady. And since the other lady had only won 3 games, that means that she must have lost an additional 3, so she had to give her candy to the other lady.
Answer:
- 3 and 3
Step-by-step explanation:
To evaluate (u ○ w)(- 1), evaluate w(- 1) then use this value to evaluate u(x)
w(- 1) = (- 1)² + 2 = 1 + 2 = 3, then
u(3) = - 3
---------------------------------------------------
To evaluate (w ○ u)(- 1), evaluate u(- 1) then use this value to evaluate w(x)
u( - 1) = - (- 1) = 1, then
w(1) = 1² + 2 = 1 + 2 = 3
1 2/3 = 5/3
4 2/5 = 22/5
5/3•22/5= 110/15
= 22/3
Answer:
Step-by-step explanation:
We first need to figure out what the equation is for this set of circumstances before we can answer any questions. We will use the equation
which is just another form of an exponential equation where
(1 + r) is the growth rate, P is the initial investment, and t is the time in years. We will fill in the values we know first to create the equation:
which simplifies to
Now we'll just sub in a 1 for t and solve, then a 2 for t and solve.
When t = 1:
A(t) = 4000(1.11) so
A(t) = 4440
When t = 2:
which simplifies to
A(t) = 4000(1.2321) so
A(t) = 4928.40
