Answer:
d ≤ - 7
Step-by-step explanation:
Given
- 38d - 57 ≥ - 19d + 76 ( add 19d to both sides )
- 19d - 57 ≥ 76 ( add 57 to both sides )
- 19d ≥ 133
Divide both sides by - 19, reversing the symbol as a result of dividing by a negative quantity.
d ≤ - 7
The answer is 8 hope this helps all u have to do is figure out what two numbers added togher give you 18
Answer:
at least 20 rows.
Step-by-step explanation:
when you add the students, teachers, and chaperones, it comes to 159. then you divide 159 by the number of seats each row has, so 159/8 = 19.875, you would have to round to the nearest whole number so 20 should be correct.

12x 21/ 8 = 31.5
Answer: 12
Step-by-step explanation:
6c + 11= 2c + 59

6c - 2c = 59 - 11
4c = 48
c = 48/4
c = 12
