Answer: Huhhhhh? That is confusing
It is 25/3 which gives you 8.3 but let's say it is 8. So 8 students have 3 siblings and 9 have 2-0 siblings and 8 have 4-any number higher siblings. So if that kid joins there would be an avg of 3.63 siblings so 3.63 is the answer.
Answer:
a=50 degrees
Step-by-step explanation:
Look at the triangle in the middle. You can find two missing angles to calculate the third one.
50 and 130 are supplementary, so 50 must be the upper right angle. The angle opposite to 80 has to be equal to it, of the upper left angle is 80.
A triangle is 180 degrees total, and 180-(50+80)= 50.
The missing angle for the triangle is 50, and since "a" is opposite to it, the values are equal.
a=50 degrees
Answer:
CAB = CAD + DAB
161 = (5X + 7) + (3X - 6)
161 = 8X + 1
160 = 8X
160/8 = 8X/8
X = 20
The equation is 1/3X+5=17 so Amanda would be 4 years old
