Answer 1

The table below shows the ticket rates for whale watching trips offered by Dolphin Tricks & Tours:

Age Ticket Price
Under three years free
Three to 12 years $35
Over 12 years $46

On a certain day, the company took 88 people on whale watching trips. There were 44 children aged 12 and under, of which some children were under three years. If x represents the number of children under three years, which equation can be used to find the value of x, where C represents the total amount of money collected from tickets that day?

Answer 2

A system of equations is shown below:

6x - 5y = 5
3x + 5y = 4

The x-coordinate of the solution to this system of equations is _____.

Answer 3

The table below shows two equations:

Equation 1 |3x – 1| + 7 = 2
Equation 2 |2x + 1| + 4 = 3


Which statement is true about the solution to the two equations?

Equation 1 and equation 2 have no solutions.

Equation 1 has no solution, and equation 2 has solutions x = 0, 1.

The solutions to equation 1 are x = -1.3, 2, and equation 2 has no solution.

The solutions to equation 1 are x = -1.3, 2, and equation 2 has solutions x = 0, 1.

Answer 4

the absolute values (in the vertical lines) are POSITIVE
so isolate these in both equations by adding 7 and 4 in equations 1 and 2 respectively and see what you get

Answer 5

* oops - sorry - subtract 7 and 4 - not add

Answer 6

3

Answer 7

no solution to either equation
