3x + 8(2) = 19, 3x + 16= 19 , 3x=3 , x =1
Answer:
42
Step-by-step explanation:
Given m and n are parallel:
x + 138 = 180 because these angles are supplementary
subtract 138 from both sides
x = 42

Answer:
Step-by-step explanation:
given that a certain test preparation course is designed to help students improve their scores on the LSAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 6 students' scores on the exam after completing the course:
We find
Mean 13.66666667 = 13.7
Standard Error 1.801234145
Margin of error for 90% = 1.645*std error = 2.963
Confidence interval = Mean ±Margin of error
=(10.704, 16.630)
Sample mean = 13.7
First you need to set this problem up as a cross multiply fraction set (actually forgot the name of it so I described it as that).
10/15 * 30/x
Solve for X
450 = 10x
Simplify
45 = x
The Daily dose is 30 meq/45 ml. For a 30 day supply you just multiply by 30.
1350 ml is needed for a 30 day supply.
