MissionMisión · Summit TrailSendero a la cumbre
Every checkpoint gets you higher.Cada punto de control te lleva más alto.
Welcome to the Summit Trail. Every checkpoint hides a number that was multiplied or divided on the way up. Use the opposite operation on both sides to find it, then check your footing.
Te damos la bienvenida al sendero a la cumbre. Cada punto de control esconde un número que se multiplicó o se dividió en el camino. Usa la operación opuesta en los dos lados para hallarlo y luego comprueba tu paso.

- inverse operationoperación inversa
- An operation that undoes another one. Multiplication and division are inverses.Una operación que deshace otra. La multiplicación y la división son inversas.
- coefficientcoeficiente
- The number in front of a letter. In 3x, the coefficient is 3.El número que está delante de una letra. En 3x, el coeficiente es 3.
- isolatedespejar
- To get the variable by itself on one side of the equation.Dejar la variable sola en un lado de la ecuación.
- Division Property of EqualityPropiedad de división de la igualdad
- Dividing both sides by the same nonzero number keeps the equation balanced.Dividir los dos lados entre el mismo número distinto de cero mantiene equilibrada la ecuación.

- A detective splits 54 clues equally among 9 case files. The equation 9c = 54 represents this. What is c?
- c = 6
- c = 9
- c = 45
- c = 63
- Spot the Common Mistake
- Vault A is sealed with 4x = 32. Crack the lock: what is x?
- x = 8
- x = 28
- x = 36
- x = 128
- What is the best next move?
- Multiply both sides by 6.
- Subtract 6 from both sides.
- Divide both sides by 6.
- Divide 6 by 54.
