This means that the number is positive.
The absolute value is the distance away from 0 the number is.
So 1's absolute value would be 1, yet -5's absolute value would be 5.
So the number that's equal to its absolute value is positive, and the one that's not is negative.
So if you subtract 2 from the positive number, it must turn negative.
So 1 is a number that satisfies these conditions.
Sq.root of 1240 is approx 35 mm
8• (5+x) < 56
That is the equation
2.41+6(0.41)+(lb-7)0.39=7.99
2.41+2.46-2.73+0.39lb=7.99
0.39lb=5.85
lb=15
The package of books weights 15 pounds...
There is 15 bars in each case.
Subtract 8 from 143 and you get 135.
Divide 135 by 9 and you get 15 :)
