Answer: It is 6+n=10, and n=1
Step-by-step explanation:
Answer:
1 < x < 2
Step-by-step explanation:
2 < 3x - 1 < 5
Add 1 to each side
2+1 < 3x - 1+1 < 5+1
3 < 3x < 6
Divide all sides by 3
3/3 < 3x/3 < 6/3
1 < x < 2
Answer:
The length is approximately 8 feet.
Step-by-step explanation:
Since the side across from the 30 degree angle is HALF the side across from the 90 degree one, then we can write this equation (supposing the height of the building is x):
x^2 + 7^2= (2x)^2
x^2 + 49 = 4x^2
x= 4
since the length is 2x, it equals 4*2 = 8
D because if u subtract 2870-24 you get 2,828 and it says about how many so to round it off you would get 2,820 so the answer is d
