Answer:
-22 ans -46
Step-by-step explanation:
3x – 8 ≤ 46 add 8 to the both sides
3x ≤ 54 divide both sides by 3
x ≤ 18 if x is equal or smaller than 18 the values -22 and -46 can make the inequality true
Answer:
2
Step-by-step explanation:
x(60) = 12(10) -->
x(60) = 120 -->
x = 2
Plane averaged 88mph with the wind and 44 against the wind. the average of these two averages is 66 mph. plane speed in still air is 66 and the wind speed was 22 (88-22=66 and 44+22=66)
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.
a₁ = 1
aₙ = 4 aₙ₋₁
The explicit formula is:
aₙ = 1 (4)ⁿ⁻¹
