Answer: i don't know but thanks for the points
Step-by-step explanation:
1/6 + 2/3 + 1/4
1) Get the least common denominator
multiple of 6: 6, 12, 18, 24
multiple of 3: 3, 6, 9, 12
multiple of 4: 4, 8, 12
LCD is 12
1/6 * 2/2 = 2/12
2/3 * 4/4 = 8/12
1/4 * 3/3 = 3/12
2) Add the numerators and put the sum above the LCD.
2/12 + 8/12 + 3/12 = 13/12
3) Simplify the fraction.
13/12 is an improper fraction, it can only be simplified resulting to a mixed fraction.
13/12 = 1 1/12
1/6 + 2/3 + 1/4 = 1 1/12
Answer:
STEP
1
:
Equation at the end of step 1
(5r2 - 14r) + 8
Step-2 : Find two factors of 40 whose sum equals the coefficient of the middle term, which is -14 .
-40 + -1 = -41
-20 + -2 = -22
-10 + -4 = -14 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -10 and -4
5r2 - 10r - 4r - 8
Step-4 : Add up the first 2 terms, pulling out like factors :
5r • (r-2)
Add up the last 2 terms, pulling out common factors :
4 • (r-2)
Step-5 : Add up the four terms of step 4 :
(5r-4) • (r-2)
Which is the desired factorization
Final result :
(r - 2) • (5r -4)
You need 710 ft of fencing.
Answer:
x = 27
Step-by-step explanation:
4(x−9)=4(9+1/3x).
Divide each side by 4
(x−9)=(9+1/3x)
Subtract 1/3 x from each side
x - 1/3x -9 = 9+1/3x -1/3x
2/3x -9 = 9
Add 9 to each side
2/3x -9+9 = 9+9
2/3x = 18
Multiply each side by 3/2
3/2 * 2/3x = 18*3/2
x = 27
