Answer:
A measures 72 and B measures 108
Step-by-step explanation:
If the angles are supplementary, that means that they add up to equal 180. 3x + 12 + 4x + 28 = 180. Doing some algebra there gives you that 7x = 140 and x = 20. Sub in 20 to angle A to get 3(20) + 12 = 72, and sub in 20 to angle B to get 4(20) + 28 = 108. And of course, 108 + 72 = 180.

Answer:
Step-by-step explanation: the pattern is going positive to negative and going further away from zero so the next term would be -3
Answer:
las fracciones decimales son:
21/10 = 2,1
439/100 = 4,39
34/10 = 3,4
35/1000 = 0,035
851 / 1000 = 0,851
Step-by-step explanation:
Toda fraccion cuyo denominador (el numero de abajo) es multiplo de 10 es considerada una fraccion decimal. No importa si el numerador es mayor al denominador. Justamente el sistema decimal fue concebido para facilitar la multiplicacion y division de los numeros por algun multiplo de 10.
