Answer:

x = 7 and x = -1

Step-by-step explanation:

<u>Step 1:  Factor</u>

x^2 - 6x - 7 = 0

(x - 7)(x + 1) = 0

(x - 7)(x + 1) = 0

x - 7 = 0 and x + 1 = 0

professor190 [17]

Answer:

The bottle will last for 20 days.

Step-by-step explanation:

Given that:

Number of drops in a dose = 4 drops

Dose is taken three times a day, therefore,

Number of drops taken in a day = 4*3 = 12 drops

One milliliter = 20 drops

12 mL = 20*12 = 240 drops

Number of days the bottle will last can be find out by calculating total number of drops by the number of drops consumed in a day.

Number of days bottle will last = \frac{240}{12}=20

Hence,

The bottle will last for 20 days.

jeka57 [31]

Answer:

33.34%.

Step-by-step explanation:

Given that,

The actual price of the shirt = $36

Price on sale = $24

We need to find the percent of the decrease. The formula for the percentage is given by :

\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100

Putting all the values,

\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%

So, the percentage decrease in the price of the shirt is 33.34%.
