-28 because if you add 8 to -120 you get -112 then divide it by 4 and you got -28

Add back the 8 to see what it was before the problem is solved. -120+8=112 the divide by 4 cause it’s the opposite of multiplying. -112/4=-28 and you can go back and check it by doing -28*4=-112-8=-120

laura has a mass of 60kg and is sitiing 265cm from the fulcrum of a seesaw. bill has a mass of 50kg. how far from the fulcrum mu

pickupchik [31]

Answer:

318 cm.

Step-by-step explanation:

Let x represent the distance between Bill and fulcrum.

We have been given that Laura has a mass of 60 kg and is sitting 265 cm from the fulcrum of a seesaw. Bill has a mass of 50 kg.

To balance the seesaw, the product of Laura's weight and her distance from fulcrum of seesaw should be equal to the product of Bill's weight and his distance from fulcrum of seesaw as:

$50\text{ kg}\cdot x=60\text{ kg}\cdot 265\text{ cm}$

$\frac{50\text{ kg}\cdot x}{50\text{ kg}}=\frac{60\text{ kg}\cdot 265\text{ cm}}{50\text{ kg}}$

$x=\frac{6\cdot 265\text{ cm}}{5}$

$x=\frac{6\cdot 53\text{ cm}}{1}$

$x=318\text{ cm}$

Therefore, Billy should be 318 cm far from the fulcrum to balance the seesaw.

The walls of a square room need painting. Each of the four walls is 12ft wide by 8.5 feet tall. One gallon of paint covers 75ft

boyakko [2]

Do 8.5 times 12, which gives you 102. Multiply by 4 and get 408. Divide this by 75 and you get 5.44. You will need 6 gallons or 5.44 gallons if you don't need to round up.
