Answer:
36π
Step-by-step explanation:
Since we are given the equation and the value for m, we can plug it into the equation to solve for the area:
Area = πm²
Area = π6²
Area = 36π
Answer: A
Step-by-step explanation: this was on my test so here is the answer
Writing the equation that governs this situation:
-3C - (2.5C/hr)x = -18C
Simplifying, -3 - 2.5x = -18, or 3 + 2.5x = 18
Combining like terms: 2.5x = 18-3 = 15
Then x = 15/2.5 = 6. The temp. will reach -18C after 6 hours.
Answer: 2 the first one
Step-by-step explanation:
This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!
