<h3><u>The length is equal to 17.</u></h3><h3><u>The width is equal to 7.</u></h3>
l = 3 + 2w
2l + 2w = 48
Because we have a value for l we can plug it into the second equation to find the exact value of w.
2(3 + 2w) + 2w = 48
Distributive property.
6 + 4w + 2w = 48
Subtract 6 from both sides.
4w + 2w = 42
Combine like terms.
6w = 42
Divide both sides by 6.
w = 7
We can plug this value for w back into the original equation to find the value of l.
l = 3 + 2(7)
l = 3 + 14
l = 17
Answer:
2 and 3
Step-by-step explanation:
The square root of 8 is 2.82842712475
1/6 percussion
1/3 wood winds = 2/6 (which is twice as many as percussion)
1/2 brass = 3/6 (which is three times as many as percussion)
So percussion = 3
wood winds = 6
brass = 9
all together = 3 + 6 + 9 = 18
X=30
