Peggy had three times as many quarters as nickels. shr had $1.60 in all. how many nickels and how many quarters did she have?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2

Given the equation −4  = 12, solve for x and identify if it is an extraneous solution.
