You can solve it like this
2=milk (a); 1=milk (b)
9=tea (a); x= tea (b)
2:9=1:x (then multiply means and the extremes)
(means are 9 and 1; extremes are 2 and x)
9=2x
9/2= x
4.5 or 4 1/2=x
Therefore, using 1 litre of milk, we can have 4 1/2 tea.
The measurement of angle b is 128°
Answer:
6/2
Step-by-step explanation:
(y2-y1)/(x2-x1)
4-(-2) over 1-(-1)
4+2 over 1+1
6/2
