6x + x + x - 5 - 2 = 8 + 2x + x
combine like terms
8x -7 = 8 +3x
subtract 3x from each side
5x -7 = 8
add 7 to each side
5x = 15
divide by 5
x=3
Answer: 8x -7 = 8 +3x
x=3
Answer: No, because 4(2) + 4 ≠ 9
Step-by-step explanation:
No, because 4(2) + 4 ≠ 9
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
Answer:
It is 2 hours, 22 minutes, 48 seconds.
The 2 is obviously 2 hours. For the minutes, .38 * 60 = 22.8, so the minutes is 22. 0.8 * 60 = 48. So 2 hours, 22 minutes and 48 seconds.
