When added, these two angles are supplementary, meaning that their sum is 180. This means that we can do the following to find x, and eventually DBC:
3x+67+4x+50=180
Simplifies to:
7x+117=180
Then by the Subtraction Prop. of Equality:
7x=63
Then divide by 7 on both sides to get that x=9.
We then substitute 9 into angle DBC.
4(9)+50
=36+50
DBC=86

Answer:
220 automóviles
Step-by-step explanation:
Aquí, queremos saber la cantidad de autos que ingresarán al garaje cuando esté completamente ocupado.
De la pregunta, nos dicen que hay 3 pisos. Para el 1er piso, hay 5 filas de 20 lugares.
El número total de autos que pueden estar en esto será 5 * 20 = 100 autos.
Para el segundo y tercer piso, tenemos 4 filas de 15 cada una.
El número total de autos aquí será 2 (15 * 4) = 2 * 60 = 120 autos
El número total de automóviles cuando está completamente ocupado es, por tanto, = 100 + 120 = 220 automóviles

Answer:
Rational
Step-by-step explanation:
A rational number can be written as a fraction of the form.
and a and b are integers.
Hence in this case a=999 and b=100.
Since both are integers with b being a non-zero integer, we conclude that 9.99 is a rational number.
