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.
The numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9
<h3>How to determine the
numbers that are 0.6 unit from 1.3 on the
number line?</h3>
The number is given as:
Number = 1.3
The distance is given as:
Distance = 0.6
The numbers that are 0.6 unit from 1.3 on the number line are represented as:
Number = 1.3 ± 0.6
Expand
Number = (1.3 - 0.6, 1.3 + 0.6)
Evaluate
Number = (0.7, 1.9)
Hence, the numbers that are 0.6 unit from 1.3 on the number line are 0.7 and 1.9
