Let’s label Mark’s marbles as ‘x’ and don’s as ‘y’.
so Don has 1 more than 2 times ‘x’.
This is written as:
y=2x+1
73 is the sum of ‘x’ and ‘y’, so x+y=73.
To solve for x, substitute our equation for y:
x+(2x+1)=73
Simplify:
3x=72
x=24
Now that we have x, solve for y:
y+24=73
y=49
Mark has to sell 24 marbles,
Don has to sell 49 marbles

Answer:
I think the answer is 18.
A line can be named either using two points on the line (for example, ↔AB ) or simply by a letter, usually lowercase (for example, line m ). A line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line.
Answer: The correct answer is B) 21%
Step-by-step explanation:
This is a binomial model probability problem. We need to find the probability of 6 out of 10 new births at a hospital being boys. The information we need is the number of trials observed, the number of successes and the percentage chance you have of any birth being a boy. The number of trials are 10, with the number of successes being 6 (the number of trials we want to be boys) It states that 51% or 0.51 of all births in the US are boys so we can use this value to determine our answer using our binomial model formula. After simplifying we get our answer of 21% I hope this has been of use to you :)
Have a wonderful rest of your day!
