Laura's piano teacher estimated that her monthly piano practice should take her 4 3/4 hours per week. Laura said that last week she practiced for 192 minutes, which she says is more than 4 3/4 hours. How much more or less did Laura practice piano than what her teacher estimated? (60 minutes = 1 hour)

432

Step-by-step explanation:

60 minutes is one hour

60 times 4=240

=240+192=432

Laura practiced the piano leass than what her teacher estamated  

Step-by-step explanation:

if you divide 192/60 you will get 3.2 so laura practiced for 3.2 hours last week which is less than what her teacher estamated.  

Formula divide the time value by 60

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

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

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
