The system of equations can be used to find the cost of a night's stay and the cost of a meal is:
2n + 5m = $395
5n + 11m = $959
<h3>
Simultaneous equations</h3>
Simultaneous equations are two or more groups of equations. These equations have to be solved together at the same time in order to determined the required valued. The two above equations have to be solved in order to determine the cost of a night's stay and the cost of a meal.
The methods of determining the required values are:
- Elimination method
- Graph method
- Substitution method

Answer:
-x^7
Step-by-step explanation:
we are given
martians =4
plutonians =3
jupiterians=5
so, total number of seats =4+3+5=12
number of seating arrangement for martians is 4!
number of seating arrangement for plutonians is 3!
number of seating arrangement for jupiterians is 5!
total number of seating arrangement is 12!
so, we get
possible seating arrangements are

Answer:
Step-by-step explanation:
Triangle IJK is a right angle triangle.
From the given right angle triangle
JK represents the hypotenuse of the right angle triangle.
With ∠K as the reference angle,
IK represents the adjacent side of the right angle triangle.
IJ represents the opposite side of the right angle triangle.
To determine Cos K, we would apply trigonometric ratio
Cos θ = adjacent side/hypotenuse. Therefore,
Cos K = 36/85
Cos K = 0.4235
Rounding up to the nearest hundredth,
Cos K = 0.42
