1. When ever the denominator have the power is negative then flip it to numerator so
3x6/9 simplified equal x6/3
2. 6/5k^10 w^3
The formula to find the perimeter of a rectangle is
When we put in our givens to this formula:
Combine x values:
Simplify right side:
Isolate x, by dividing both sides by 10:
To find length:
For width:
To solidify our answers:
So, our length is 153, our width is 102.
19 quantities of item A and 6 of item B were sold, respectively
<h3>How to determine the quantity sold</h3><h3>The missing information in the question are</h3>
- The cost of item A is $4 and
- The cost of item B is $2.
Using the information and the given parameters, we have the following system of equations:
A + B = 25
4A + 2B = 88
Multiply the first equation by 2
2A + 2B = 50
Subtract this equation from the second equation to eliminate B
2A = 38
Divide both sides by 2
A = 19
Substitute A = 19 in A + B = 25
19 + B = 25
Subtract 19 from both sides
B = 6
Hence, 19 quantities of item A and 6 of item B were sold, respectively
