Step-by-step explanation:
4th is <u>16</u>
6th is <u>36</u>
By pythagoras
53^2 = h^2 + 45^2 where h is the height of the television.
h^2 = 53^2 - 45^2 = 784
h = sqrt 784 = 28 inches Answer
Answer:
x+y = 3
3x-y = 5
Step-by-step explanation:
x+y = 3
3x-y = 5
This system of equation will give the points(2,1).
Lets substitute the values x=2 and y = 1 in the equations:
x+y=3 equation 1
2+1 =3
3=3
3x-y=5 equation 2
3(2)-1=5
6-1=5
5=5
Lets solve the system:
Add the equations to eliminate y from the system:
x+y = 3
3x-y = 5
_______
4x = 8
Now divide both the sides by 4
4x/4 = 8/4
x=2
Now substitute the value of x in equation 1:
x+y=3
2+y=3
Combine the constants:
y=3-2
y=1....
178
You add 85cm plus 258cm plus 13cm then you get the answer divide it by 2 you get
178cm
