Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 7 mo than 3 times the number of marbles Mark has, how many does each boy have to sell if the total numbe
of marbles is 103?
Mark has Number
marbles to sell.
Don has Number
marbles to sell.

Mark has 24

Don has 79

Step-by-step explanation:

Let x = marbles mark has

don has 3x+7

Together they have 103

mark + don = 103

x+ (3x+7) = 103

Combine like terms

4x+7 = 103

Subtract 7

4x = 96

Divide by 4

x = 96/4

x =24

Mark has 24

Don has 103 -24

Done has 79

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.
