Answer:
x=70, y=55
Step-by-step explanation:
Since the angle "y" and 2x-15 form a straight line, that means the sum of the angles, must be 180 degrees.
So using this we can derive the equation: 
The next thing you need to know is that the sum of interior angles of a triangle is 180 degrees, so if we add all the angles, we should get 180.
So using these we can derive the equation: 
So, in this case we simply have a systems of equations. We can solve this by solving for x in the second equation (sum of interior angles), and plug that into the first equation.
Original Equation:
Subtract 2y from both sides
Now let's plug this into the first equation
Plug in 180-2y as x
Distribute the 2
Combine like terms
Subtract 345 from both sides
Divide both sides by -3
So we can plug this into either equation to solve for x
Substitute in 55 as y
Subtract 110 from both sides

Answer:
The number of sleeping bags bought is 17.
Step-by-step explanation:
If we let "x" be the number of the sleeping bags that were bought, we can make the following equation....
(5x)(12) + (x)(45) = 1785
By solving the equation we get....
(5x)(12) + (x)(45) = 1785
60x + 45x = 1785
105x = 1785
x = 1785 / 105
x = 17
There for the number of sleeping bags bough is 17.
Answer:
Step-by-step explanation:
The formula to use for this is
For us,
A(t) = 4300
P = 3800
n = 4
t = 2
r = ?
Let's fill in what we have then:
which simplifies a tiny bit to
The first thing to do is to divide both sides by 3800 to get
Now take the 8th root of both sides (on your calculator, of course!) to get
Now subtract 1 from both sides to get
And multiply both sides by 4 to get
.0622869598 = r
Multiply by 100 to get the rate as a percentage. It rounds to
r = 6.23%
