Answer:
steps below
Step-by-step explanation:
x < -10
|1+2x| < 0 ∴ |1+2x| = -(1+2x)
|5 − 3x| > 0 ∴ |5 − 3x| = 5-3x
|−5x − 8 | > 0 ∴ |−5x − 8 | = -5x-8
|1 + 2x| + |5 − 3x| − |−5x − 8 |
= -(1+2x) + (5-3x) - (-5x-8)
= (-2x - 3x + 5x) + (-1 + 5 + 8)
=<u> 12</u>
Answer:
x = 13 1/2 days
Step-by-step explanation:
1/2 acre 2 1/4 acre
------------ = -------------------------
3 days x days
using cross products
1/2 * x = 2 1/4 * 3
change 2 1/4 to an improper fraction (4*2+1)/4 =9/4
1/2 x = 9/4*3
1/2x = 27/4
multiply each side by 2
2 * 1/2 x = 27/4 * 2
x = 27/2
change back to a mixed number
x = 13 1/2
1275 divided by 588= 2.168367346938776
