Matt gave 5 apples to his son and sold 8 times as many apples. If Matt had 1/2 of the apples left, how many did he have in the beginning?

90

Step-by-step explanation:

8*5 = 40

40 + 5 = 45

1/2 x = 45

x = 90

90 apples

Step-by-step explanation: If Mat sold 8 times as many apples as how much he gave to his son, this means he sold 40 apples.  Altogether, he loses 45 apples (5 to his son, 40 sold), and this is 1/2 of the original numbers of apples.  Hence, the original number of apples was 90

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
