Therefore the reminder is 3 when 5n is divided by 7.
Step-by-step explanation:
we know that
Dividend = quotient × Divisor +Reminder
⇔ n = Q(n) × 7 + 2 [ let Q(n) is quotient]
multiplying by 5 both sides
5n = 5 Q(n) ×7 + 2×5
⇔5n = 5 Q(n) ×7 +10
⇔5n= 5 Q(n) ×7 +7 +3
⇔ 5n = (5Q(n) +1) × 7 +3
Therefore the reminder is 3 when 5n is divided by 7.
5 is a common factor on both of them
Answer:
n = 16
Step-by-step explanation:
3^4(81^2) = 3^n
3^4(3^4) = 3^n
3^16 = 3^n
n = 16

Answer:
180M (1 round); 900M (5 rounds)
Step-by-step explanation:
Solve for perimeter with is 2L + 2 W.
1. 2(50) + 2 (40) =
2. 100 + 80 = 180
He walked 180M for 1 complete round. To determine 5 complete rounds, multiply by 5.
180X5= 900 M
