1. Un examen de Matemáticas ha sido aprobado por 12/18 de los estudiantes. Al resto les toca repetir el examen. Si el grupo está compuesto por 90 estudiantes, ¿cuántos de ellos deben repetir dicho examen?

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

i just used a calculator

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
