Answer:
5
Step-by-step explanation:
1. Add -8 to -12. This equals -20.
2. Now you have -20/(-4)
3. Solve this by dividing -20 and -4.
4. Two negatives make a positive, so your answer would be 5.

Answer:
Cost = 40.00 + 26.00c + 15.00b
Step-by-step explanation:
Let c = number of canoe rentals
and b = number of bicycle rentals. Then
Annual pass = 40.00
Canoe rentals = 26.00c
Bicycle rentals = 15.00b
Total cost = 40.00 + 26.00c + 15.00b
Answer:
a) possible progressions are 5
b) the smallest and largest possible values of the first term are 16 and 82
Step-by-step explanation:
<u>Sum of terms:</u>
- Sₙ = n/2(a₁ + aₙ) = n/2(2a₁ + (n-1)d)
- S₂₀ = 20/2(2a₁ + 19d) = 10(2a₁ + 19d)
- 2020 = 10(2a₁ + 19d)
- 202 = 2a₁ + 19d
<u>In order a₁ to be an integer, d must be even number, so d = 2k</u>
- 202 = 2a₁ + 38k
- 101 = a₁ + 19k
<u>Possible values of k= 1,2,3,4,5</u>
- k = 1 ⇒ a₁ = 101 - 19 = 82
- k = 2 ⇒ a₁ = 101 - 38 = 63
- k = 3 ⇒ a₁ = 101 - 57 = 44
- k = 4 ⇒ a₁ = 101 - 76 = 25
- k = 5 ⇒ a₁ = 101 - 95 = 16
<u>As per above, </u>
- a) possible progressions are 5
- b) the smallest and largest possible values of the first term are 16 and 82
