Answer:
5 ft
Step-by-step explanation:
Denote the height of the previous jump as j. Therefore, it follows that 1.1j equals 5.5 ft.
By dividing both sides by 1.1, we derive j = 5 ft. This indicates the height from the prior jump.
Answer:
Step-by-step explanation:
Let c denote the total number of children present at the concert.
Let a indicate the total number of adults who attended the concert.
During one concert, every adult accompanied 4 children, while 10 children came unaccompanied. Therefore, the equation representing the children is
c = 4a + 10
The prices for tickets were set at $5 for each child and $8 for every adult. The overall revenue from ticket sales amounted to $1730. This generates the equation
5c + 8a = 1730
Consequently, the set of equations to find the number of children, c, and adults, a, that were present at the concert is
c = 4a + 10
5c + 8a = 1730
