P = 2(L + W)
P = 96
L = 2W + 8
96 = 2(2W + 8 + W)
96 = 2(3W + 8)
96 = 6W + 16
96 - 16 = 6W
80 = 6W
80/6 = W
40/3....or 13 1/3 ft <== width
L = 2W + 8
L = 2(40/3) + 8
L = 80/3 + 8
L = 80/3 + 24/3
L = 104/3 or 34 2/3 <== length
Answer:
The value of x is 2 and y is (-5)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
- -7x + y = – 19
- -2x + 3y = – 19
<h3><u>To </u><u>Find</u>;</h3>
<h3><u>B</u>y<u> </u><u>Usin</u>g<u> </u><u>Elimination</u><u> </u><u>Method</u>;</h3>
First name the equation
- -7x + y = – 19 ...(1)
- -2x + 3y = – 19 ...(2)
Now, Multiply equation (1) by 3 we get,
3 × (-7x + y = – 19)
-21x + 3y = – 57
Now, Eliminate
-21x + 3y = – 57
-2x + 3y = – 19
<u>+</u><u> </u><u> </u><u> </u><u> </u><u>–</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u>+</u><u> </u><u> </u><u> </u><u> </u>
-19x = -38
x = -38/-19
x = 2
Now, Put the value of x in equation (2) we get the value of y.
-7x + y = – 19
-7(2) + y = – 19
-14 + y = -19
-14 + 14 + y = -19 + 14
y = -5
Thus, The value of x is (-5) and the value of y is 2.
<h3>
<u>For </u><u>Verification</u>;</h3>
-7x + y = – 19
-7(2) + (-5) = – 19
-14 – 5 = – 19
-19 = -19
-2x + 3y = – 19
-2(2) + 3(-5) = – 19
-4 – 15 = – 19
-19 = -19
Here, L.H.S = R.H.S
Hence Verified!

Answer:
1680 miles
Step-by-step Explanation:
There are 52 weeks in a year. Total number of days she is expected to work would be 52 * 5 = 260 days.
Now we know she has 10 vacation days and 10 holidays. This translates 260 - 20 = 240 days
Now if she drives 35miles 5 days of the week, this means she dives 7 miles per day.
The total number of miles traveled is this 240 * 7 = 1680 miles
Answer:
what do you exactly want me to do? rewrite the equation or solve it?
