Answer:

A

Step-by-step explanation:

Given 60% of students passed , then 40% of students failed.

Which of these strategies would eliminate a variable in the system of equations? \begin{cases} 6x + 5y = 1 \\\\ 6x - 5y = 7 \end
IRISSAK [1]

Answer:

x = 0.667 and y = -0.6

Step-by-step explanation:

Given that,

6x + 5y = 1 ....(1)

6x - 5y = 7 ...(2)

We need to solve the above equations.

Subtract equations (1) and (2)

6x + 5y -(6x - 5y) = 1-7

6x+5y-6x+5y = -6

10y=-6

y = -0.6

Put the value of y in equation (1).

6x + 5(-0.6) = 1

6x = 1-5(-0.6)

6x = 4

x = 0.667

Hence, first step is to subtract equation (1) and (2) then put the value of y in equation (1).

alukav5142 [94]

Answer:

62. 84%

Step-by-step explanation:

total revenue of a company from music sales and licensing in 1999 = $14.8 billion

Foretasted  total revenue of a company from music sales and licensing in 2014  = $5.5 billion

decrease in revenue of a company from music sales and licensing in 2014  from 1999 =  $14.8 billion - $5.5 billion = 9.3 billion

Therefore percentage decrease in music revenue =( difference in revenue from 1999 to 2014/   revenue in 1999 ) * 100

 (9.3 \ billion/14.8 \ billion) * 100\\=> 0.6284 *100 \\=> 62.84 %\\

percent decrease in music revenue is 62. 84%.
