The sum of fifteen and a number
Answer:
Step-by-step explanation:
I believe you do, 4 times each number in the absolute value symbol. 4 times n, 4 times positive 8. 4n+32=56
You minus 32 on both sides and you get 24. Then you take 24 and divide it by 4, and there is your answer 6.
You can check it by plugging 6 into the equation.
Step-by-step explanation:
Part A: The temperature must be greater than -40, and lower than 140. -40 < T < 140
Part B: The graph is a number line between -40 and 140, with open circles at -40 and 140. The solutions are temperatures at which the gas will remain liquid.
Part C: No, -49 is less than -40, so the gas would have frozen.
25/5 = 5......so the unit rate is 5 teaspoons per cup
