Answer:
42.5 if rounding 43 for B
Step-by-step explanation:
P is the variable so put 100 under it
Then on the first empty fraction put 17/40
Cross multiply
You will get 40p=17x100
So then you multiply 17 by 100
1700
divided both sides by 40
Get the variable alone
Divide 1700 by 40
get 42.5
If your teacher is as annoying as mine round to 43
The total number of elements is 2+2=4. Since we have 2 silver earrings, we get
the, the probability to get two silver earrings is 1/2, which is equivalent to 0.5.

SOLUTION:
Step 1:
The length of a rectangular garden is 8 feet longer than its width.
If the garden's perimeter is 184 feet.
What is the area of the garden in square feet?
Step 2:
L = length
W = width
L = W+8
P = perimeter
P = 2(L+W)
P =184 (given)
Substitute L=W+8 in the perimeter equation
2( (W+8) + W ) = 184
(W+8) +W = 92
2W + 8 = 92
2W = 84
W = 42 ft ( Width = 8 feet )
L = W+8
L = 42+8
L = 50 ft ( Length = 50 feet )
Always check your work.
In this case, check the perimeter.
2(L+W) = ?
2(50+42) = 184 feet.
CONCLUSION:
Then, the question says:
It asks for the area in square feet.
A = Area
A = L*W
A = 50 ft * 42 ft
A = 2100 sq ft.
