<u>Correct Question</u>
In the table shown, the sum of each row is shown to the right of the row and the sum of each column is shown below the column. What is the value of L?
Answer:
L=7
Step-by-step explanation:
From the first row: 2J+K=5
Therefore: K=5-2J
From the second column, 2K+J=7
Substitute K derived above into 2K+J=7
2K+J=7
2(5-2J)+J=7
10-4J+J=7
-3J=7-10
-3J=-3
J=1
Recall: K=5-2J
K=5-2(1)=3
K=3
From the third column, J+2L=15
1+2L=15
2L=15-1=14
L=7
Therefore, the value of L=7
CHECK:
A acute angle is always less than 90 degrees. So the answer is A.
There is 4 1/10's in 2/5.
You do this by turning 2/5 into a fraction with a denominator of 10, so it will be 4/10. 1/10 + 1/10 + 1/10 + 1/10 = 4/10
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions
<h3>Linear equations</h3>
Linear equation are equation that has a leading degree of 1. Given the equation that represents Statins used to keep cholesterol in check and are a top-selling drug in the U.S.
S-1.5x = 6
where
S is the amount of sales
x is the number of years after 1998
By 2017, the total number of years is 19 years
Substitute
S = 1.5x + 6
S = 1.5(19) + 6
S = 28.5 + 6
S = 34.5
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions
