3x-4 is the answer, you have to see that if its 3 times her nieces age it would be 3x and if its four less than that it is 3x-4
I think it would be 3 because if you divide 18/6=3
Hello! The ratio would be 15 minutes warm ups: 65 minutes total workout.
To simplify this: 3:13 ratio. (Divided 15 by 5 and 65 by 5)
A.) a right triangle would have 2 acute angles.
b.) there would be 0 obtuse angles.
c.) there would be 1 right angle.
In the diagram you can see a little black box in one of the corners of the triangles. That box means the angle is a right, 90 degree angle. Since an acute angle is an angle that is less than 90 degrees, and since all three angles would have to add up to 180 degrees, you know that the other two angles are acute angles.
