Answer: 7
Step-by-step explanation:
Here the given inequality that shows the number of humming birds(H) and the number of sunbirds(S) that must pollinate the colony so it can survive until next year,
6 H + 4 S > 74
If This year, 8 hummingbirds pollinated the colony.
By putting H=8 in the above inequality,
We get,
6× 8 + 4 S > 74
⇒ 48 + 4 S > 74
⇒ 4 S > 26
⇒ S > 6.5
Hence the least number of sunbirds is 7.
Answer:
x = - 2 or x = 4
Step-by-step explanation:
the expression inside the absolute value can be positive or negative
Removing the bars and solve x - 1 = ± 3
x - 1 = - 3 or x - 1 = 3
x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2
x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4
Answer:
x < 3
Step-by-step explanation:
Since 3x - 5 < 4 then we can transpose the inequality to make x the subject of the equation:
If 3x - 5 < 4
⇒ 3x < 4 + 5
⇒ x < 9 ÷ 3
⇒ x < 3
