21/4+55/6+32/3 simplify
Answers
Rules in adding fraction.
1) Get the Least Common Denominator.
multiple of 4: 4, 8, 12
multiple of 6: 6, 12, 18
multiple of 3: 3, 6, 9, 12 Least Common Denominator is 12.
21/4 * 3/3 = 63/12
55/6 * 2/2 = 110/12
32/3 * 4/4 = 128/12
2) Add the numerators and place the sum above the least common denominator
63/12 + 110/12 + 128/12 = (63+110+128)/12 = 301/12
3) Simplify the fraction
301/12 is an improper fraction. To simplify an improper fraction, a mixed fraction will result.
301/12 = 25 1/12
421/4 + 55/6 + 32/3 = 63/12 + 110/12 + 128/12
= (63 + 110 + 128)/12 = 301/12 = 25 1/12
The correct result is 301/12 or 25 1/12.
Hope that helped =D

Rounding to two significant figures the number became
Step-by-step explanation:
Given : Number 8,468
To find : Round this number to two significant figure ?
Solution :
Rounding to two significant figure we have to estimate or round the values in terms of zeros.
Rounding the number to hundreds value,
As 6 is greater than 5 so 4 rounds to 5 and rest became zero.
i.e.
bar means the estimated value.
Therefore, Rounding to two significant figures the number became

The equation -2(6 - 20n) = 20(2n - 3) has no solution.
Hence the correct option is C.
Given is an equation -2(6 - 20n) = 20(2n - 3), we need to solve it for n,
Let's solve the equation step by step:
-2(6 - 20n) = 20(2n - 3)
First, distribute the -2 on the left side and the 20 on the right side:
-12 + 40n = 40n - 60
Next, let's move all the terms with "n" to one side of the equation:
-12 + 40n - 40n = 40n - 40n - 60
-12 = -60
Now, we can see that the equation is inconsistent, as there are no values of "n" that satisfy this equation.
Therefore, the correct answer is:
c. no solution

-12 + 40n = 40n - 60
40n = 40n - 60 + 12
40n - 40n = 60 + 12 (dont minus 40n - 40n yet, we can factorise it)
n(40-40) = 60 + 12
n = (60 + 12)/(40-40)
n = 60 + 12/ 0
Therefore no solution as we cannot divide by 0

The Answer is C) 2, -6
Step-by-step explanation:
Look at the graph as you can see there is only one solution to that graph and on the line intersected there is one point which that would be 2, -6.
Note: Understand that when asking about the point or something else look for the lines intersected each other then you could find your answer. If there is only one line then it is infinite solutions but if the lines don't intersect then it is a no solution.
Have a good day :)
