706,421 rounded to the nearest thousand is 706,000 because the 421 is less than 500 so the 6 would remain a 6.
Answer:
w<6 THE SMALL LINE UNDER THE LESS THAN SIGN IS STILL THERE I JUST CANNOT ADD IT
Step-by-step explanation:
first solve the equation to the right.
-3(2w+1) = -6w-3
now solve the whole equation
-33-w< -6w-3
-w+6w < -3+33
5w < 30
divide the 5 from both sides to simplify
5/5w < 30/5
w < 6
THE ANSWER IS w < 6
Answer:
17,37
Step-by-step explanation:
one number = x
The positive number = 2x + 3
x * (2x+3) = 629
x*2x + x *3 = 629
2x² + 3x - 629 = 0
2x² - 34x + 37x - 17*37 =0
2x*(x -17) + 37(x - 17) = 0
(x - 17)(2x + 37) = 0
x - 17 = 0 ; Ignore 2x + 37 as s is a positive number
x = 17
Positive number = 2*17 +3 = 34+3 = 37
Average thickness of book = Total thickness/mo. of books
= 28 cm/ 10
= 2.8 cm
Thus, on average, each book has 2.8 cm thickness.
