Answer:
x = -3/2
Step-by-step explanation:
The correct option for this question would be C.
2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
Born: 7.45 pounds
gains: 6.4 oz a week
time: 1.5 months
6.4 + 6.4 + 6.4 + 6.4 + 6.4 + 6.4 = 38. 4 oz
38.4 oz = 2.4 punds
7.45 + 2.4 = 9.85
The answer is letter C. Because the y-intercept which is -2 and the slope is negative(which it should go down 2 steps). Originally the slope is rise over run which is 2/4 simplified as 1/2 or -1/2.
