Answer:
1 ≤ x < 7
Step-by-step explanation:
−2+3≤x−3+3<4+3 (Add 3 to all parts)
Answer:
- points on the boundary line: (0, 10), (20, 0)
- solution points not on the boundary line: (100, 100)
Step-by-step explanation:
We cannot tell from the posted picture whether the boundary line is solid or dashed, so the answer above is split into two parts. If the boundary line is solid (x+2y≥20), all three listed points are in the solution set. If the boundary line is dashed (x+2y>20), only (100, 100) is in the solution set.
210 I think because theres 3.4 of 60minutes/ hrs and 3.4 times 60 is 209.6 and it said round to the nearest minute which is 9 so 210
Subtract 42 from 44.92 and then divide by 42. So it is 7%
Answer:
We just have to solve each power.

Remember, to solve a power, we just need to multiply its base as many times indicates its exponent.
It's important to know that the negative exponent indicates a position, that's why in the second exercise we needed to change the position of the power to continue.
