Answer:
1.2
Step-by-step explanation:
1
=1.2
Let x be the 1st odd number, and x+2 the second odd consecutive number:
(x)(x + 2) = 6[((x) + (x+2)] -1
x² + 2x = 6(2x + 2) - 1
x² + 2x = 12x +12 - 1
And x² - 10x - 11=0
Solve this quadratic expression:
x' = [+10 +√(10²- 4.(1)(-11)]/2 and x" = [+10 -√(10²- 4.(1)(-11)]/2
x' = [10 + √144]/2 and x" = [10 - √64]/2
x' = (10+12)/2 and x" = (10-12)/2
x = 11 and x = -1
We have 2 solutions that satisfy the problem:
1st for x = 11, the numbers at 11 and 13
2nd for x = - 1 , the numbers are -1 and +1
If you plug each one in the original equation :(x)(x + 2) = 6[((x) + (x+2)] -1
you will find that both generates an equlity
Answer:
6/7 - 1/3
Step-by-step explanation:
You know that 1/2=0,5
Then, you have to solve the two sums:


You now know what number of 0,47 and 0,52 is closer to 0,5; which is 0,52
0,47 is to 0,03 from 0,5
0,52 is to 0,02 from 0,5
product - result of multiplication
quotient - result of division
sum - result of addition
difference - result of subtraction
Step-by-step explanation:
(3, -2)
(x, y) → ((x - 5), (y + 6))
(3, -2) → ((3 - 5), (-2 + 6))
(3, -2) → (-2, 4) which is the third option
