Answer:
x = 15
Step-by-step explanation:
Now multiply both sides by 3
-4x = -20*3
-4x = -60
Divide both sides by (-4)
x = -60/-4
x = 15
3+√x+19-√2x replace x by 6===> 3+√6+19-√2*6 = 3+√6+19-√12
Note that √12 = √2x6 = √2 x √6 ===>3+√6+19-(√2) x (√6)
=√6(1+√2)+22
Answer:
About 68% will make between $200000 and $240000.
Step-by-step explanation:
C. About 68% will make between $200000 and $240000. If the standard deviation is $18,000, then add that to $225000. That equals $243000. Subtract $18000 from the average, you end up with $207000. So it is close, but about 68% will make between $200000 and $240000.
Answer:
1/8
Step-by-step explanation:
8x-3=-2
8x-3+3=-2+3
8x=1
divide both sides by 8
x=1/8
