Answer:

7, 13, 19, 25, 31

Step-by-step explanation:

aₙ = 6n + 1

n = 1: a₁ = 6 × 1 + 1 = 6 + 1 = 7

n = 2: a₂ = 6 × 2 + 1 = 12 + 1 = 13

n = 3: a₃ = 6 × 3 + 1 = 18 + 1 = 19

n = 4: a₄ = 6 × 4 + 1 = 24 + 1 = 25

n = 5: a₅ = 6 × 5 + 1 = 30 + 1 = 31

Julie and Eric row their boat (at a constant speed) downstream for 40 miles in 4 hours, helped by the current. Rowing at the sam

Liula [17]

Answer: 3 miles per hour

Step-by-step explanation:

Use the formula "distance (d) = rate (r) x time (t)" to create a system of equations.

Let "r" represent the rate they are rowing

Let "c" represent the current

time rate distance EQUATION

Downstream: 4 hours r + c 40 miles 4(r + c) = 40

Upstream: 10 hours r - c 40 miles 10(r - c) = 40

Distribute, then eliminate r to solve for c:

Down: 4r + 4c = 40 → 5(4r + 4c = 40) → 20r + 20c = 200

Up: 10r - 10c = 40 → -2(10r - 10c = 40) → -20r + 20c = -80

40c = 120

÷40 ÷40

c = 3
