Answer:3/8y+(6x+4)
Step-by-step explanation:
I’m 99% sure to is is right
50
there’s no way x is 360 or 140
The 2 angles add up to 90 degrees so
x + y = 90, also:-
x - y = 72 (given)
adding the 2 equations:-
2x = 162
x = 81
and therefore
y + 81 = 90
y = 9
Answer the 2 angles are 81 and 9 degrees
A is aldult tickets
b is child tickets
b = 2/3 a
7a + 12b = 90
7a + 12 x 2/3 a = 90
7a + 8a = 90
15a = 90
a = 6; b = 4
Y = 3x + 13
You can get this by using the same slope and then plugging into the equation to find the intercept. <span />
