Answer:
y = 15
Step-by-step explanation:
Given: y varies directly with x, x=4 when y=20
To find: y when x = 3
Solution:
As y varies directly as x, it means that as x increases, y also increases by the same factor.
As y varies directly with x,

Here, k is a constant
As x = 4 when y = 20,

Put x = 3

Answer:
11
Step-by-step explanation:
Answer:
2:1 =36mm: x m
2/1 = 36mm/ m......(Criss cross)
36mm x 1M/2mm = 18 Meter
Y + 79 + 37 = 180
y + 116 = 180
y = 64
Answer:
x = 42
Step-by-step explanation:
The angle between the tangent and the secant is
difference of the measure of the intercepted arcs, that is
x = 0.5( 136 - 52) = 0.5 × 84 = 42
