Answer: Mark has 28 marbles while Don has 85 marbles.
Step-by-step explanation:
Let x represent the number of marbles that Mark has.
Let y represent the number of marbles that Don has.
If Don has 1 more than 3 times the number of marbles Mark has, it means that
y = 3x + 1
The total number of marbles is 113. It means that
x + y = 113- - - - - - - - - - - - 1
Substituting y = 3x + 1 into equation 1, it becomes
x + 3x + 1 = 113
4x + 1 = 113
4x = 113 - 1 = 112
x = 112/4
x = 28
y = 3x + 1 = 3 × 28 + 1
y = 85
Answer:
104, 106
Step-by-step explanation:
Hello!
A consecutive number is a number that comes after the other.
Let the first even integer be x. Since there is an even integer for every two integers, the second number should be x + 2.
<h3>Solve for x</h3>
- (x) + (x + 2) = 210
- x + x + 2 = 210
- 2x + 2 = 210
- 2x = 208
- x = 104
The second number is x + 2, so it would be 106.
