liraira [26]

$\frac { 1 }{ x } +\frac { 1 }{ 4 } =\frac { 7 }{ 12 } \\ \\ \frac { 1 }{ x } =\frac { 7 }{ 12 } -\frac { 1 }{ 4 }$

$\\ \\ \frac { 1 }{ x } =\frac { 7 }{ 12 } -\frac { 3 }{ 12 } \\ \\ \frac { 1 }{ x } =\frac { 4 }{ 12 } =\frac { 1 }{ 3 } \\ \\ 3x\cdot \frac { 1 }{ x } =\frac { 1 }{ 3 } \cdot 3x\\ \\ x=3$

You buy school clothes during a sale when everything in the store is 15% off. Which of the following could describe

Savatey [412]

Answer:

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0

Step-by-step explanation:

The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;

Actual cost - (Percentage discount) Actual cost = Total cost

The correct options are;

(29.99 + 18.65 + 32.59) 0.85 = 0

(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
