Answer: The system of linear equations are
L + W = 45
L = 4W - 5
Step-by-step explanation:
Let L represent the length of the deck.
Let W represent the width of the deck.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2( length + width)
The perimeter of a rectangular wooden deck is 90 feet. This would be expressed as
90 = 2(L + W)
Dividing through by 2
L + W = 45
The deck's length,L is 5 less than 4 times its width, W. This is expressed as
L = 4W - 5
Answer:
None.
Step-by-step explanation:
4(x-1)-x = 3(x+5)-11
4x-4-x=3x+15-11
we combine like terms.
4x-x-4=3x+14
3x-4=3x+14
we then isolate the variables.
3x-4=3x+14
+4 +4
3x=3x+18
-3x -3x
0≠18

Answer:
The probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.
Step-by-step explanation:
Given that a bag contains 3 red, 3 white and 3 green balls, to determine, if one ball is taken out of the bag at random, what is the probability that the ball drawn is (1) red, (2) not red, or (3) either red or white, the following calculations must be performed:
1)
3/9 = 0.333 x 100 = 33.33%
2)
6/9 = 0.666 x 100 = 66.66%
3)
6/9 = 0.666 x 100 = 66.66%
Therefore, the probability that the ball is red is 33.33%, it is not red 66.66%, and red or white is 66.66%.
<u>Answer:</u>
The correct answer option is 48.
<u>Step-by-step explanation:</u>
In the given experiment, three events take place which include rolling a die, flipping a coin and spinning a spinner.
The possible outcomes of each of these events are as follows:
Rolling a die - 6
Flipping a coin - 2
Spinning a spinner - 4
Therefore, by multiplying their possible outcomes, we can find the number of elements in the sample space of this environment.
Number of elements = 6 × 2 × 4 = 48
