Remember
if |a|=b then assume a=b and a=-b
divide boths ides by -3
|2x+6|=4
assume
2x+6=4 and 2x+6=-4
minus 6 both sides
2x=-2 and 2x=-10
divide by 2
x=-1 and x=-5
2nd option
4x=5x-3
+3 +3
4x+3=5x
-4x -4x
3=x
Answer:
2) 1 dozen apple ( 12 apples ) = $4.92
1 apple = $4.92/12
= $0.41
3) distance = speed × time
= 9/10 × 10
= 9 miles
4) 61 minutes = 183 pages
1 minute = 3 pages
5) 8 days = 7 boats
1 day = 7/8 boats
6) speed = distance/ time
= 288/4
= 72 miles/hour
7) 5 cup of flour = 4 cups of sugar
1 cup of flour = 4/5 cup of sugar
The answer would be:
( ab + 50 ) • ( ab - 50 )
