X= my age
500-3x=230
500-3x-230=230-230
270-3x=0
270-3x+3x=0+3x
270=3x
270/3=3x/3
x=90

We know that all angles of a triangle equal 180 when added together. We have two angle measures which are 3/2x and 1/2x
***3/2x + 1/2x + x = 180 degrees***
For the other way you can switch around the positions of the angles in the equation as long as the = stays 180 so like
X + 3/2x + 1/2x = 180
180 + x + 1/2x + 3/2x
Or maybe change the 3/2x to 1 1/2x

Answer:
x=14 y=6
Step-by-step explanation:
Answer:
y = 26
Step-by-step explanation:
Write the direct variation equation.
y = ax
Substitute y for 6 and x for 4.
The new equation is:
6 = a(4)
Simplify:
6 = 4a
Divide by 4 on both sides to get a = 6/4.
________________________________
y = 6/4(24), 6/4 x 24 is 104/4. 104/4 is 26.
y = 26
