Answer:

10%

Step-by-step explanation:

Machine out put power =100 watt

Machine input power=1000 watt

We have to find the efficiency of the machine.

We know that

Efficiency of machine=\frac{O.p}{I.p}

Where O.p=Output power

I.p=Input power

By using the formula

Efficiency of machine=\frac{100}{1000}=0.1

Efficiency of machine (in percent)0.1\times 100=10%

Hence, the efficiency of machine=10%

3(1.5x+9)= tell me NOW
Misha Larkins [42]

Answer:

x = -6

Step-by-step explanation:

Simplifying

3(1.5x + 9) = 0

Reorder the terms:

3(9 + 1.5x) = 0

(9 * 3 + 1.5x * 3) = 0

(27 + 4.5x) = 0

Solving

27 + 4.5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + 4.5x = 0 + -27

Combine like terms: 27 + -27 = 0

0 + 4.5x = 0 + -27

4.5x = 0 + -27

Combine like terms: 0 + -27 = -27

4.5x = -27

Divide each side by '4.5'.

x = -6

Simplifying

x = -6

Solve for m y-y=m(x-x)
spin [16.1K]

Answer:

m = y/x

Step-by-step explanation:

y-y = m(x-x)

simplify:

-2y = m(-2x)

simplify again

-2y = -2mx

divide to get rid of -2 and x

-2y = -2mx

----------------

-2x

y

-  = m
