He subtracted incorrectly
Step-by-step explanation:
You multiply 42.75 x 4 and get 171. Then you add 171+52.45=223.45 and then you subtract 223.45-18=205.45 and then you multiply 223.45 x .3333 = 68.3265 or 68.33 (rounded)
Answer:
B: (-8/3 , 8)
Step-by-step explanation:
A (x₁,y₁) (4,-7) and C (x₂,y₂) (-4,11), B (x,y)
AB (a):BC (b) = 5:1
x = (bx₁ + ax₂) / (a+b) = (1*4+5*-4) / (5+1) = -16/6 = - 8/3
y = (by₁ + ay₂) / (a+b) = (1*-7+5*11) / (5+1) = 48/6 = 8
B: (-8/3 , 8)
