Answer:

$62.10

Step-by-step explanation:

To calculate how much the employee's discount actually was, we just multiply the original price by the discount

Plug the prices in --> 138 x 45/100

Simplify 45/100 --> 9/20

138/1 x 9/20 = 1242/20

1242/20 = 62.1

62.1 = $62.10

and thus, the discount is $62.10

Insturctions to care for a plant say to water it with 3/4 cup of water every day.The plant has been getting 25% too much water.
disa [49]

For this case we propose a rule of three. We assume that the excess water received was in one day. So:

\frac {3} {4} cup ------> 100%

x ----------------------------> 25%

Where "x" represents excess water.

x = \frac {25 * \frac {3} {4}} {100}\\x = \frac {\frac {75} {4}} {100}\\x = \frac {75} {400}\\x = \frac {15} {80}\\x = \frac {3} {16}

Thus, the excess water is \frac {3} {16}cups.

Then, in one day you receive in total:

\frac {3} {4} + \frac {3} {16} = \frac {16 * 3 + 4 * 3} {16 * 4} = \frac {48 + 12} {64} = \frac {60 } {64} = \frac {15} {4}cups of water.

Answer:

\frac {15} {4} cups of water

Solve 2(x + 1) = 2x + 5.
ANTONII [103]

Answer:

There are no solutions

Step-by-step explanation:

2(x+1)=2x+5

Distribute the values on the left:

2x+2=2x+5

subtract 2x from each side

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

2=5

These value are not equal so there are no solutions
