Answer:
Step-by-step explanation:
Tips = 20% of 47.60
= (20/100) * 47.60
= 0.20 * 47.60
Total bill = 47.60 + (0.2)*(47.60)
-3(3y-2x)+ 2(5x-4y)
-9y+6x+10x-8y
-17y+16x
So the answer is D.
Answer: length = 28 meters
Width = 15 meters
Step-by-step explanation:
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The rectangular garden is enclosed with eighty-six meters of fencing. This means that
2(L + W) = 86
Dividing through by 2, it becomes
L + W = 43- - - - - - - - - - - -1
The garden is thirteen meters longer than it is wide.. This means that
L = W + 13
Substituting L = W + 13 into equation 1, it becomes
W + 13 + W = 43
2W + 13 = 44
2W = 43 - 13
2W = 30
W = 30/2
W = 15
L = W + 13 = 15 + 13
L = 28
P (Not a 2) = P(2) + P(3) + P(4)
P(1) = 0.30
P(3) = 0.15
P(4) = 0.15
So,
P( Not a 2) = 0.30 + 0.15 + .15 = 0.60
So, the answer to this question is option D
