198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604
frequency = 1 + 3 +2 + 5 + 2 = 13
201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x
x = 2814 = 2604 +x
subtract 2604 from both sides:
x = 2814 - 2604
x = 210 cm
height of new player = 210 cm
Answer:
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Step-by-step explanation:
We need to solve the linear system of equations.

We can write second equation y=x-4 as: 
Let:

Now, Adding equation 1 and 2

So, we get x = 1
Now, put value of x in second equation to find value of y:

So, we get y = -3
Solving the given linear system, we get x = 1 and y = -3.
The solution set is: (1,-3)
Same case as Pablo's, more or less.
a = price for the desktop
b = price for the laptop
we know the laptop is 150 bucks more than the desktop,
b = a + 150.
how much is 7% of a? (7/100) * a, 0.07a.
how much is 9.5% of b? (9.5/100) * b, 0.095b.
total interests for the financing add up to 303,
0.07a + 0.095b = 303.

how much was it for the laptop? well b = a + 150.
Answer:1)720 white stripes and 840 red stripes
2)48 divided by 4=12 feett per second
3)265 divded by 4 than divide 425 by what you got before
4)3 times 10=30
Step-by-step explanation:
We now look at a right-angled triangle with sides a, b and c, as shown opposite. Pythagoras' Theorem states that, for any right-angled triangle, the area of the square on the hypotenuse is equal to the sum of the areas of the squares on the two shorter sides.
