4. The legs of an isosceles triangle have lengths 3x + 3 and -x + 15. The base has length 2x - 3. What is the length of the base?

3

Step-by-step explanation:

The legs are congruent which means:

3x + 3 = -x + 15

4x = 12

x = 3 which means the base is 2x - 3 = 2(3) - 3 = 3.

Step-by-step explanation:

here x= 3

therefore substitute x=3 in base lenght

ie 2x -3 = 6-3 =3

therefore base length = 3

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
