Can someone explain please

See below

Step-by-step explanation:

A number is divisible by 4 if the last two digits are divisible by 4.

A number is divisible by 8 if the last three digits are divisible by 8.

So for the first one, the digit would either be 7 or 1 because 72 is divisible by 4 and 12 is divisible by 4. If you notice, 72-12=60, which is also divisible by 4.

For the second one, the digit would be either 1 or 9 because 112 is divisible by 8 and 192 is divisible by 8. If you notice, 192-112=80 which has an 8 in it!

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

answer: all of the odd numbers were opened
