the perimeter, p, of an equilateral triangle varies directly as the length of a side. if the perimeter is 153 cm when the side length is 51 cm, what would be the perimeter if the side length is 81 cm

What is the probability of rolling a single die greater than 4

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Change negative exponents to positive. then solve. round to four decimal places
