Answer:
The number is 45.
Step-by-step explanation:
2/3x=30
x=30/(2/3)
x=(30/1)(3/2)
x=90/2
x=45
Answer:
y ≤ (1/2)x + 2
Step-by-step explanation:
Find the equation of the solid line. It is immediately evident that the y-intercept is (0, 2). The line also passes through (-4, 0). Starting at (-4, 0), x (the run) increases by 4 to 0 and y (the rise) increases from 0 to 2. Thus, the slope of this line is m = rise / run = 2/4, or m = 1/2.
Thus the equation of the line is y ≤ (1/2)x + 2.
The Answer is D. It is the x-values.
O que posso acrescentar é que 3 linhas de segmentos reflexivas no triângulo definem o baricentro... estas 3 linhas serão as medianas do triângulo e o baricentro divide as linhas em 3 partes iguais.
