Answer: The employees in a firm earn $8.50 an hour for the first 40 hours per week, and 1.5 ... purchase 4 lb steak for $3.89 per pound, 4 dozen eggs for $1.05 per dozen, 2 gallons of milk for $1.99 per gallon, and 3 loaves of bread for $1.79 per loaf
Step-by-step explanation:
Hello,
the first step should be to distribue:
-4(3-5x)= -12+20x
Teh resolution may be:
-4(3-5x)>=-6x+9
==>-12+20x>=-6x+9
==>20x+6x>=9+12
==>26x>21
==>x>=21/26
But an other way may be used:
-4(3-5x)>=-6x+9
==>3-5x<= -6x/(-4)+9/(-4)
==>-5x-3/2 x<=-9/4 -3
==>-13/2 x <=-21/4
==>x>= -21/4 *(-2/13)
==>x>=21/(2*13)
==>x>=21/26
The distributive property is a(b + c) = ab + ac
