Answer:

see below

Step-by-step explanation:

The two terms 9 and -10 can be combined to give -1.

The two terms 2x and -18x can be combined to give -16x.

Fully simplified, the expression would be ...

-16x +14y -1

Anything with different coefficients is not equivalent. Anything with only one pair of terms combined is "not fully simplified."

A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use

agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T = minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031
