What is the difference between an equation and expression?
Cual es la diferencia entre una ecuacion y una expresion?
an equation has an equal sign allowing it to be solved. an expression is a combination of numbers, operation symbols, variables without an equal sign needed.
una ecuacion tiene un signo de = que permite resolverla. una expresion tiene numeros, variables y simbolos de operacion, sin necesitar un signo de =What is an inequality?
Que es una desigualdad?
compares numbers using symbols like > (greater than) and < (less than), and can be graphed on a number line.
Compara números utilizando símbolos como > (mayor que) y < (menor que), y se puede representar gráficamente en una recta numérica.
What is a scale factor?

a number that determines how much larger or smaller a shape becomes. (using times)
un numero que determina cuanto mas grande o pequeno se vuelve una figura. (usando multiplicacion)
SOLVE # 2

D.13
11 X 3= 33
60-33 = 27
27/2 = 13.5

B. 150%
Multiply side 12 cm x 150% = 18 cm
so the factor is 150% which is 1.5
SOLVE # 1
RESUELVE #1
A. 20 units; 2.5 units
I multiplied 250% x 8 = 20 (got bigger horizontally) and then multiplied 50% x 5 = 2.5 (got smaller vertically)
Multiplique 250% x 8 = 20 y despues multiplique 50% x 5 = 2.5
SOLVE #8
RESUELVE #8
4000 X 3/4 = 3000 METERS
4000 X .75= 3000
