-6/5x+2=21/25 anyone?
2 answers:
Solve:
-6/5x + 2 = 21/25
Steps:
Solution -6/5x + 2 = 21/25 =======> 29/30, Decimal =====> x = 0.96667
Subtract 2 from both sides:
-6/5x + 2 - 2 = 21/25 - 2
Simplify:
-6/5x = -29/25
Multiply both sides by -25:
(-6/5x )(-5) = (-29/25 )(-5)
Simplify:
6x = 29/5
Divide both sides by 6:
6x/6 = 29/5/6
Simplify:
Answer x = 29/30 Decimal: 0.96667....
Hope that helps!!!! : )

The constant of proportionality in terms of the cost per text is the coefficient of 
in the equation 
. Since the coefficient of is 0.25, the constant of proportionality in terms of the cost per text is 0.25.
Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:
Finally, we can simplify our fraction:
We can conclude that the constant of proportionality in text of the cost per text is 1/4

The rate of change is 16.8 million tons per year
<em><u>Solution:</u></em>
Given that, the world catch of fish in 1950 was 12 million tons and in 1955 it was 96 million tons
<em><u>The average rate of change is given by formula:</u></em>
Value in 1950 = 12 million tons
Value in 1955 = 96 million tons
Change in value = value in 1955 - value in 1950
Change in value = 96 million - 12 million = 84 million tons
Number of years = 1950 to 1955 = 5 years
<em><u>Substitute the given values in formula,</u></em>
<em><u></u></em><em><u></u></em>
Thus rate of change is 16.8 million tons per year
