What is the value of x in the equation Negative StartFraction 6 over 7 EndFraction = Negative StartFraction x over 84 EndFraction? –98 –72 72 98

The correct answer is 72

Step-by-step explanation: The expression given as negative Start fraction 6 over 7 End fraction simply means

-6/7

Also the expression given as Negative Start fraction x over 84 simply means

-x/84

So the equation properly written out reads thus;

-6/7 = -x/84

By cross multiplication, we now have

-7x = -84 x 6

-7x = -504

Divide both sides of the equation by -7

x = 72

**Note that dividing a negative number by another negative number results in a positive answer**

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock

0 and 5 minutes

step-by-step explanation:

given that one morning eight buses arrive late by the number of minutes given below:

0 8 2 6 9 2 0 7 8

write these in ascending order

0   0 2 6 7 8 8 9

in the afternoon two more buses arrive at the bus stop say by x and y minutes late.

total number of buses = 10

median = average of 4th and 5th after arranging in ascending order

since 4th entry is 6, the values of x and y should be below 6

also given 0 is the mode so either x or y or both should be 0 because then only 0 gets the maximum frequency and hence mode

thus we have

0 0 0 2 6 7 8 8 9 and another unknown entry which is below 6.

since median is 3.5, we have the unknown entry to be 5 only because then only median =( 2+5)/2

thus the after noon buses were late by 0 and 5 minutes.
