Fill in the blank 1. x-7> 10 x> 2. 3x ≤ 21 x ≤ 3. 5a-2< 18 a< 4. 2t + 8 ≥ -4(t+1) t≥

Answer with Step-by-step explanation:

1. x-7>10

Adding 7 on both sides,we get

x>17

2. 3x ≤ 21

Dividing both sides by 3,we get

x≤7

3. 5a-2<18

Adding 2 on both sides, we get

5a<20

Dividing both sides by 5,we get

a<4

4. 2t + 8 ≥ -4(t+1)

Distributing -4 on right hand side of inequality

2t+8 ≥ -4t-4

2t+4t ≥ -4-8

6t ≥  -12

Dividing both sides by 6, we get

t ≥ -2
