Answer:

$3x+5 < n < x-1$

Step-by-step explanation:

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the Triangle Inequality Theorem

1) $(2x+2)+(x+3) > n$

solve for n

$3x+5> n$

Rewrite

$n$

2) $(x+3)+n> 2x+2$

$n> x-1$

therefore

$3x+5 < n < x-1$

If -1 is one of the roots of the equation 3x² - 2k - 2x - 1 = 0, find the value of k.

snow_tiger [21]

Answer:

k = 2

Step-by-step explanation:

Given that x = - 1 is a root of the equation, then it satisfies the equation.

Substitute x = - 1 into the equation and solve for k, that is

3(- 1)² - 2k - 2(- 1) - 1 = 0

3 - 2k + 2 - 1 = 0

- 2k + 4 = 0 ( subtract 4 from both sides )

- 2k = - 4 ( divide both sides by - 2 )

k = 2

A local amusement park charges $21.50 per daily adult ticket and $14.75 per daily child's ticket. A group of 12 people paid $204

grandymaker [24]

Answer:

$x+y=12$

$21.50x+14.75y=204$

Step-by-step explanation:

Let x be the number of adult tickets and y be the number of children's tickets.

We are given that there are total 12 people. Therefore, we can set:

$x+y=12$

Moreover, we are given that an adult ticket costs $21.50 and a child's ticket costs $14.75, therefore, cost of x adult tickets will be $21.50x$ and cost of y children's ticket will be $14.75y$ . We can form the second equation by setting the total cost of tickets as:

$21.50x+14.75y=204$

Therefore, the required system of equations that could be used to find x and y will be:

$x+y=12$

$21.50x+14.75y=204$
