Answer: a=-0.75
Step-by-step explanation:
14a - (2a +9)=2/3 (12a-18)
14a - 2a -9=2/3 * 6(2a-3)
12a-9=2*6/3 (2a-3)
12a-9=2*2(2a-3)
12a-9=4(2a-3)
12a-9=8a-12
4a-9=-12
4a=-3
a=-3/4
a=-0.75
Answer:
D. 46 minutes 12 seconds
Step-by-step explanation:
To find the answer, we need to calculate the least common multiple of 252,308 and 198
252=
×
×7
308=×7×11
198=2××11
Then <em>least common multiple</em> is
××7×11=2772 seconds
2772 = 46×60 + 12
Therefore 2772 secondsis equal to 46 minutes 12 seconds.
The answer should be 126 or A.
The lines are perpendicular if their slopes are negative reciprocal of the other.
Since 9/2 is just a reciprocal and not the NEGATIVE reciprocal of 2/9, the lines are NOT perpendicular.
