1/4t + 9 = 3
Subtract 9 from both sides
1/2t= -6
Divide 1/2 on both sides so that the only thing remaining on the left side is the variable t.
Final Answer: t= -12

It is so simple Hope u understand
Answer:
option 1
Step-by-step explanation:
Both of these have the same number of solutions (which is 2)
Remember that |5x + 6| means "the absolute value of the expression '5x + 6'", so in this case, 5x + 6 could equal 41 or -41 since the absolute value would "strip away" the positive or negative sign and leave just the number
So, if you solve:
5x + 6 = 41
5x = 41 - 6 = 35
x = 35 / 5 = 7
5x + 6 = -41
5x = -41 - 6
5x = -47
x = -47 / 5
Do the same thing for the other expression:
2x + 13 = 28
2x = 28 - 13 = 15
x = 15 / 2
2x + 13 = -28
2x = -28 - 13
2x = -41
x = -41 / 2
So, both of these expressions have two solutions.
Hope this helps!
Good luck.
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.
