Answer:
she will earn $6,657 in interest in 3 years
B - 7x = a - b
Subtract b from both sides.
-7x = a - 2b
Divide both sides by -7.
x =
Using the perimeter of a rectangle, it is found that she can make a deck of 122 ft wide.
<h3>What is the perimeter of a rectangle?</h3>
The perimeter of a rectangle of length l and width w is given by:

In this problem:
- She has enough wood to build a deck that is 280ft, hence P = 280.
- The length is of 10 feet, hence l = 10.
- Considering that the deck's width will be added to the actual width of 8 feet, we have that w = 8 + w.
Then:






She can make a deck of 122 ft wide.

Answer:
y= -1/3x+5
Step-by-step explanation:
-1/3 is the slope (rise/run)
5 is the y-intercept
Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
