Which of the following is the solution set to the inequality −2/5x+14>20?
1 answer:
Answer:
x < - 15
Step-by-step explanation:
Given
- x + 14 > 20 ( subtract 14 from both sides )
- x > 6 ( multiply both sides by 5 to clear the fraction )
- 2x > 30
Divide both sides by - 2, reversing the inequality symbol as a result of dividing by a negative quantity.
x < - 15
solution set is x ∈ (- ∞, - 15)

Answer:
Total distance = 30.3 units
Step-by-step explanation:
Coordinates for the location of Alanah, Mia, Teresa and Arena are,
Alanah → (2, 8)
Mia → (8, 16)
Teresa → (8, 2)
Arena → (14, 4)
Distance between two points and
is given by the formula,
d =
Distance between Alanah and Mia =
=
= 10 units
Distance between Mia and Teresa =
= 14 units
Distance between Teresa and Arena =
=
= 6.3 units
Total distance of Alanah's trip to Arena = 10 + 14 + 6.3
= 30.3 units
