A 30-foot-long support wire for a 16-foot high streetlight runs from the top corner of a building to a point on the ground, forming a straight line. The length of the wire from the top of the building to the top of the street light is 6 feet. How tall is the building?
I think the answer is 20 ft
Subtract x/a from both sides.
y/b=1-x/a
Multiply by b on both sides.
y=b(1-x/a)
If you want, you can leave it like that or you can distribute the b through.
y=b-bx/a
1 yard=3 feet so 14 feet=4 yards and 2 feet
Answer:
Step-by-step explanation:
Let the Price of TV set be x.
The price of computer = x - 5200
x + x - 5200 = 105200
2x = 105200 + 5200
2x = 110400
x = 110400/2
x = Rs. 55200
Price of TV set = Rs. 55200
Price of computer set = 55200 - 5200 = Rs. 50000
