Answer:
7 minutes
Step-by-step explanation:
The scientist changes the temperature for the solution at a rate of -7°C per minute. We need to find out how long it'll take for the solution's temperature to change from 0°C to -49°C. So, we divide -7 by -49 to find out how long it will take:
-49 / -7 = 7
It will take 7 minutes for the temperature to reach -49°C.
It was a debate between the northerners and southerners (forgive my spelling). The northerners feared the addition of more slave states and a corresponding lack of reprenestation of their intrests in the North. For the southern slave holders, new western lands would be a boon (helpful) to enslaved people and the Louisiana purchase threatened to entrench and expand their suffering to western territories.
I got this on Khan Academy
Answer:
12,455 + x = 23,894
x = 11,439
Step-by-step explanation:
Let's say that the variable 'x' represents the salaries for the second month, so out equation would be:
12,455 + x = 23,894
To solve, we must isolate the variable by subtracting 12,455 from both sides:
12,455 + x = 23,894
-12,455 -12,455
x = 11,439
So, the second month's salary was $11,439
Hope this helps :)
