HOPE THIS HELPS I'M SO LOST>>>> Here we are working backwards. Look at questions 7 and 8 and think about how we can do the opposite process.Question 7 (\$2200 + 1.5x) 1.5*250+\$2,200 =\$2,575.00

Algebra
How many animals should be tested for the average cost to be \$3.50 per animal? 220,00 set up cost. (Remember we cannot have partial animals)

c=6350/(425-3x) What is the cost and equation to remove 99% of the pollution in the pond?

Algebra
The cost, in millions, to remove x% of pollution in a pond is modeled by the equation: . What is the cost to remove 75% of the pollution? Hint: Plug in and calculate, do not convert to a decimal. what value of x would make the equation undefined? Hint: Think about what makes a...

equation of variation is 7x.

algebra
This is easy 35 would go into 5 7 times so the answer would be variation constant is 7. this is a two part qustion the 2nd part is the same as the first but u add the x its called the equation of variation.

Algebra
Speed of passenger train is 6mph faster than the freight train. The passenger train travels 260 miles at the same time the freight train travels 230 mph. WHAT would be the speed of both the passenger and freight trains?????

Algebra
Thanks

Algebra
Can anyone solve this PPPPPlease 5/x-3 + 2/x+3= -7x/x^2-9

Algebra
Thank you so much. How can We can find the average cost per animal by dividing total costs by number of animals. Write an expression that helps solve the average cost per animal. 2200 + 1.50/x <<<would this be the answer
