I believe it’s -12w+16x+20
Answer: room 101 and room 107
Step-by-step explanation:
In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3
In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.
In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3
Therefore, room 101 and room 107 have the same ratio.
Step-by-step explanation:
|4x + 8| > 2
Therefore 4x + 8 > 2 or 4x + 8 < -2.
When 4x + 8 > 2, 4x > -6, x > -1.5.
When 4x + 8 < -2, 4x < -10, x < -2.5.
Hence, x < -2.5 or x > -1.5.
