Answer:

2. 3/4, 50%, 1/4, 12.5%

Step-by-step explanation:

Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4

1/4 = 0.25

50%

= 50/100

= 0.5

12.5%

= 12.5/100

= 0.125

3/4

= 0.75

in order from greatest to least?

3/4, 50%, 1/4, 12.5%

1. 12.5%, 1/4, 50%, 3/4

2. 3/4, 50%, 1/4, 12.5%

3. 3/4, 12.5%, 1/4, 50%

4. 1/4, 50%, 3/4, 12.5%

Dafna1 [17]
So lets take a look at what we know:

5% of the tickets were discount
100% of the tickets is equal to 60 tickets

From this information we can create the proportion:

\frac{x}{5} = \frac{60}{100}.

Cross Multiply to get 100x=300

Divide 100 on each side to get x=3 .

Three discount tickets were sold.

Solve by the substitution method.
GalinKa [24]

Answer:

The unique solution to the system is (x,y){(-9,-3)}

Step-by-step explanation:

x - y = -6     equation 1

5x + 6y = -63     equation 2

We will find the value of x from equation 1.

x= y-6

Now put the value of x in equation 2.

5(y-6)+6y = -63

5y-30+6y = -63

Combine the like terms:

5y+6y= -63+30

11y = -33

Divide both sides by 11.

11y/11 = -33/11

y = -3

Now put the value y = -3 in x=y-6

x = y-6

x= -3-6

x= -9

Therefore The unique solution to the system is (x,y){(-9,-3)} ....

how many quarts of pure antifreeze must be added to 6 quarts of a 40% antifreeze solution to obtain a 60% antifreeze solution
lora16 [44]

Answer:

3 quarts

Step-by-step explanation:

First, find how many quarts of antifreeze is in the mixture.

0.4 x 6 = 2.4

Now, make it into a fraction by putting the antifreeze amount over the rest so:

2.4/6

Now add + a at the end of the numerator and bottom to make:

2.4 + a/ 6 + a.

Now, turn the percentage you want to strengthen or weaken the mixture into a percentage. So, 3/5.

Now, make it an expression by adding = 3/5 at the end of the equation.

2.4 + a/ 6 + a = 3/5

Now, use cross multiplication.

12 + 5a = 18 + 3a

Now, solve the equation.

12 + 5a = 18 + 3a

-3a. -3a

12 + 2a = 18

-12. -12

2a = 6

/2. /2

a = 3.

Therefore, the answer is 3 quarts.
