Answer:
17.5
Step-by-step explanation:
Given that the variables x and y have a proportional relationship.
i.e. y is directly proportional to x or can be written as
y = mx where m is the constant of proportionality.
When x =2, y =7
Substitute this to get the value of m.
7 =2m or m = 3.5
Thus the relationship between x and y is
y = 3.5x
So when x=5, y = 3.5(5) = 17.5
Answer:
16 square units
Step-by-step explanation:
→ Find the area of the whole triangle
0.5 × ( 5 + 4 ) × 8 = 36
→ Find the area of the small triangle
0.5 × 5 × 8 = 20
→ Minus the area's of the triangles
36 - 20 = 16 square units
