Get like terms together. you might have to move across the equals sign
3x-x=-6+82
2x=76
x=38
All you have to do is divide 75 by .15. To start, you need to get rid of the decimal in .15, so move your decimal two spots to the right to turn .15 into 15. Then you have to move your decimal that is implied to be at the end of 75 over two spots because you moved the decimal in .15 which makes it 7,500. Now you have:
7,500 ÷ 15 = 500 500 is your answer.
Plot two points find place where they touch.
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.
