Answer:

So the answer would be 2495.

Step-by-step explanation:

We can write 499 as 500 - 1

Because we can easily multiply 500 to 5 compare to 499 to 5.

So product of 499 × 5 = (500 - 1) × 5

= 500 × 5 - ( 1 × 5 = 5 )

= 2500 - 5 = 2495

So the answer would be 2495.

Zepler [3.9K]

Answer:

10(2+3)

Step-by-step explanation:

We are given that

Ice=20 lb

Cup=30

We have to find the expression which shows the greatest common factor using distributive property of 20 and 30.

We know that distributive property of integers a,b and c

$a\cdot(b+c)=a\cdot b+a\cdot c$

$20=2\times 10$

$30=3\times 10$

$10(2+3)=10\times 2+10\times 3$

Hence, the highest common factor of 20 and 30=10

Expression:10(2+3)
