Answer:

Step-by-step explanation:
In the question, we're given that the notation
produces a number
less than the product of
and
raised to the
power. Let the number produced be
. As a mathematical equation, we can write this production as 
For
, we can assign:
Substituting these values into
, we get:

Add 2 to both sides:

Take the square root of both sides:

For
, there are two cases:

Therefore, we have:

The only answer choice applicable is
.

-4w - 3 = 9
3w + 4
<u>Step 2: Solve for </u><em><u>w</u></em>
- [Addition Property of Equality] Add 3 on both sides: -4w = 12
- [Division Property of Equality] Divide -4 on both sides: w = -3
<u>Step 3: Evaluate</u>
- Substitute in <em>w</em>: 3(-3) + 4
- Multiply: -9 + 4
- Add: -5

Answer:
n=50
Step-by-step explanation:
7/100 = 3.5/n
The fastest way to do this you can set up proportions.
7n=3.5*100 (you multiply mean and extreme)
7n=350 (you move 2 decimal places to the right)
n=350/7
n=50
Answer:
30
Step-by-step explanation:
2x + x =90
3x=90
x=90/3
x is 30
