Answer:
2x=3y or x= -3y/2 and y =2/-3y
Step-by-step explanation:
4x-2x=-3y
2x=-3y
The answer would be, 0.55555555556
hope this helps :-)
Answer:
The probability is 0.95
Step-by-step explanation:
In this question, we are interested in calculating the probability that a randomly selected student of the university recycles at least some of the times
Mathematically, the probability that student recycles at least some of time = 1 - probability that the student never recycles all the time
From the question, the probability that the student never recycles all the time = 0.05
Substituting this into the equation given above;
Probability that a randomly selected student at the university recycles at least some of the time = 1-0.05 = 0.95
Answer:
Length = 4 feet
Width = 4 feet
Step-by-step explanation:
The perimeter of a rectangle formula = 2L + 2W
Where L = Length
W = Width
The length of a rectangle is 8feet less than the width.
Hence,
L = 8 - W
The perimeter is 64 feet.
Hence,
64 = 2(8 - W) × 2W
64 =( 16 - 2W )2W
64 = -4W² + 32W
4W² - 32W + 64 = 0
Factorise
4W² - 16W - 16W + 64 = 0
4W (W - 4) - 16(W - 4) = 0
W - 4 = 0
W = 4
Width = 4
Solving for L
L = 8 - W
L = 8 - 4
L = 4
Therefore,
Length = 4 feet
Width = 4 feet
Answer:
a = 1
Step-by-step explanation:
1. distribute the -6 on the left into the parentheses. you should get -36a + 30.
2. on the side right of the =, distribute the -2 to get -16 + 10a.
now it should look like -36a + 30 = -16 + 10a.
3. move the terms over to isolate the a value. subtract 30 to the right side to get -46 (-36a=-46+10a)
4. move the 10a on the right to the left by subtracting it to the other side.
(-46a=-46)
5.divide by -46 to get a=1
