The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
Could just be used as a variable.
Answer:
Five million four thousand three hundred
Step-by-step explanation:
Answer:
x = 8/√3
Step-by-step explanation:
We solve that above question using the trigonometric function of sin
Sin theta = Opposite/Hypotenuse
Theta = 60°
Opposite = 4
Hypotenuse = x
Hence,
Sin 60 = 4/x
Cross Multiply
sin 60 × x = 4
x= 4/sin 60
in rational form
sin 60 = √3/2
Hence, x = 4/ √3/2
= 4 ÷ √3/2
= 4 × 2/√3
= 8/√3
Answer: 90
Step-by-step explanation: The mean of a data set is equal to the
sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set
shown here, begin by adding the numbers.
Adding the numbers, we get 720.
This will be divided by the number of numbers in the set, or 8.
So we have 720/8 or 90.
So the mean of the data set shown here is 90.
