Given parameters:

        1.        -\frac{7}{8}  + \frac{1}{4}  

 

         -\frac{7}{8}  + \frac{1}{4}; find the LCM = 8

 

             =    \frac{-7  +  2 }{8}        

             =     \frac{-5}{8}

   

       2.   -\frac{12}{5}  + 15.3  

            Make the fraction decimal;

             -\frac{12}{5}   = -2.4

            So;

                        -2.4 + 15.3  = 12.9

Tickets sold at a school football game cost $1.00 each if purchased before the day of the game. They cost 1.50 each if bought at
Nitella [24]

Answer:

200

Step-by-step explanation:

Let number of tickets sold before game be x while those at the gate be y

Total tickets sold are 600 hence x+y=600

Cost of tickets

Total amount collected is $700 hence

x+1.5y=700

x+y=600

x+1.5y=700

Subtracting equation 1 and 2

0.5y=100 hence y=200

The decimal point of a positive real number is moved two digits to the right to form a different real number. When the positive
tekilochka [14]

Answer: 7/3

Step-by-step explanation: let the original real number be x. After moving the decimal point of this real number two digits to the right, the number becomes 100x. The positive difference between the two numbers is 100x - x = 99x. Dividing the difference by 11, we have 99x/11 = 9x, which we are told is 21, so we have the equation 9x = 21/9, which equals 7/3. Thus, the original real number is 7/3.
