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 answer for this will be
-1/3x+3
80/100 x 30 = 24 because you just multiply percents
Answer: 975
Step-by-step explanation:
Because you multiply 6 times 150 and then you add 75 because that is half of 150 and you only need one more mile
6v-5/8=7/8
6v=12/8
v=12/8÷6
v=.25
