Answer:
x=1, y=2.5
Step-by-step explanation:
Answer: i) 30 students for chemistry
ii) 21 students for only one subject
iii) 61 students
Step-by-step explanation: from the question we got 30 students registered for chemistry. number students only for biology = (27-18) = 9
number of students only for chemistry = (30-18) = 12
number of student registered for only one subject = (12+9)= 21
number of students registered for neither two subjects = {100-(9+12+18)} = 61

Answer:
B. 24
Step-by-step explanation:
Since both triangles are similar, therefore,
GM/XD = AG/KX
(x - 2)/6 = (x + 9)/9
Cross multiply
9(x - 2) = 6(x + 9)
9x - 18 = 6x + 54
Collect like terms
9x - 6x = 18 + 54
3x = 72
Divide both sides by 3
x = 72/3
x = 24
