Which number line represents the solution set for the inequality 3(8-4x) < 6(x - 5)?
STatiana [176]

Answer:

x>3

Step-by-step explanation:

We are given with the inequation 3(8-4x) < 6(x - 5)

Dividing both sides in the above in equation by 3 we get

(8-4x)<2(x-5)

Distributing 2 over (x-5)

(8-4x)<2x-10

8-4x<2x-10

adding 10 and 4x on both hand sides we get

8+10<2x+4x

18<6x

Dividing both sides by 6 we get

3<x

Hence the solution to the given in equation is x>3

frez [133]

Answer:

397

Step-by-step explanation:

write an equation:

x = logan

y = marcus

z = janet

x = 2y

z = 1/3y+8

y = 243

x = 2 * 243

x = 486

z = 1/3 * 243 + 8

z = 89

logan = 486 contacts

marcus = 243 contacts

janet = 89 contacts

486-89 = 387

logan has 397 more
