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
Answer:
missing denominator: 5
missing numerator: 3
Step-by-step explanation:
You know the product of fractions is formed by multiplying numerators and multiplying denominators.

This gives rise to two equations:
3n = 9 ⇒ n = 3
4d = 20 ⇒ d = 5
The missing denominator is 5; the missing numerator is 3.
