Answer:
C
Step-by-step explanation:
To solve this use the equation 
given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.
Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.
So the factored form is (x-20)(x+5) = 0.
Set each factor equal to 0 and solve.
(x-20) = 0 so x = 20.
(x+5)=0 so x = -5.
This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.
Answer:
x+y = 39 and 14y+19=666
Step-by-step explanation:
Let x is the no of tickets for the weekend and y for the weekday.
The price for a weekday ticket is $7, and the price for a weekend ticket is $9.50. The rickshaw driver collected a total of $333 for the week.
Equation (1) should be :
x+y = 39 (because a rickshaw company counted 39 ticket receipts last week)
Equation (b) should be :
7y+9.5=333
Multiplying both sides by 2.
14y+19=666
Hence, the two equations that represent the situation are :
x+y = 39 and 14y+19=666
It would be D because the equation just seems flipped, but the requirements of x are fulfilled.
