Respuesta:
30
Explicación paso a paso:
Número total de preguntas = 100%
Número de preguntas correctas = 27
Porcentaje de aciertos = 90%
Por eso,
Si 90% = 27
Luego ; 100% = x
Multiplicar en cruz:
0,9 veces = 27
x = 27 / 0,9
x = 30
Número de preguntas = 30
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation of the line
To find c substitute ( , 4) into the partial equation
4 = 2 + c ⇒ c = 4 - 2 = 2
y = 3x + 2 → A
