Answer:
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
The side AB measures option 2. units long.
Step-by-step explanation:
Step 1:
The coordinates of the given triangle ABC are A (4, 5), B (2, 1), and C (4, 1).
The sides of the triangle are AB, BC, and CA. We need to determine the length of AB.
To calculate the distance between two points, we use the formula
where () are the coordinates of the first point and () are the coordinates of the second point.
Step 2:
For A (4, 5) and B (2, 1), () = (4, 5) and () = (2, 1). Substituting these values in the distance formula, we get
So the side AB measures units long which is the second option.
