Good evening ,
Answer:
B. 24
Step-by-step explanation:
y and x have a proportional relationship, and y = 24 when x = 16
then
y÷x = 24÷16 = 1.5
Since y=36 then
36÷x = 1.5
then
x = 36÷1.5 = 24.

Set 6x = 9x-27
Then solve
Answer:
3.14
Step-by-step explanation:
Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
