Answer:
P = 2l + 2w
solve for w
re-write
2l + 2w = P
subtract 2l from both sides
2w = P - 2l
divide both sides by 2
w = (P - 2l) / 2
Answer is B
w = (P - 2l) / 2
In order to write this in scientific notation, we must move the decimal from the beginning all the way to between the 5 and the 9
Note: you can move the decimal anywhere you want but typically scientific notation will have the decimal in between the first and second digit.
Since we move the decimal 24 digits to the right, our answer will be
5.972 * 10^24
or
5.972E24
Hope this helps!!
Answer:
$47.70
Step-by-step explanation:
60.00 x .25 = 15 ( so $15.00 off the shoes )
60.00-15.00 = 45.00
45.00 x .06 = 2.70 (2.70 is your sales tax so add that to you sale price )
$45.00 + $2.70 =$47.70 Total
Answer: 
Explanation:
The equation is:
The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.
This means that we can solve separately for the two terms:
Solving the first equation:
Solving the second equation:
