Answer:
y =
Step-by-step explanation:
given that y and x are proportional then the equation relating them is
y = kx ← k is the constant of proportionality
to find k use the given condition y = 12 when x = 5
k = =
y = x ← equation of proportionality
when x = 8, then
y = × 8 =
Answer:
1/3
Step-by-step explanation:
x from 3 to 1 = 1/3
y from 18 to 6 = 6/18 = 1/3
Answer:
area of the big triangle is QS*RT, where we know the QS
so we need to derive the area of big triange
the big triange is sum of the larger triangle (QT*RT) + smaller one (TS*RT)
so RT*(5+2.2)=RT(5)+RT(2.2)
the rest is simple to solve
