<u>Answer</u>:
equation: y = 24x
Step-by-step explanation:
if y and x is proportional,
y = kx
72 = k * 3
k = 24
→ Here the constant if 24
so the equation that relates x and y :
y = 24x
Answer:
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
110 and 3x - 20 are supplementary angles, sum to 180° , then
110 + 3x - 20 = 180
90 + 3x = 180 ( subtract 90 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30
