(b) What per cent is1/2<br>dozen of one score?<br>

aleksandr82 [10.1K]

Answer:

1/2 dozen of one score is 30%.

Step-by-step explanation:

As we know that 1 dozen = 12 units.

1/2 dozen = 1/2 times 12=6 units

1 score = 20 units.

By using this conversion, we get

6/2 times 100=30%

So 1/2 dozen of one score is 30%

Bruce is solving a system of equations.

Valentin [98]

Answer:

Option 3,4,5 are correct.

Step-by-step explanation:

The system of equations are:

$3x+5y=9\,\,\,\,(1)\\x-y=-5\,\,\,\,(2)$

Multiply equation (2) with -3 and add with equation (1)

$3x+5y=9\\-3x+3y=15\\-------\\8y=24\\y= 24/8\\y=3$

Value of y is 3

Putting value of y in eq(2)

$x-y=-5\\x-3=-5\\x=-5+3\\x=-2$

Value of x is -2

So, Option 3,4,5 are correct.
