1) 1.72
2)-0.4
3) if you mean 10/3-76= -72.7
if you mean 10/3-7/6= 2.2
Answer:
17
Step-by-step explanation:
They are vertical angles so they are the same angle.
51 = 3x

Answer:
7.3
Step-by-step explanation:
You have to make this a pythagorean theorm equation.
so you would have a side length of 7 and 2.
7^2+2^2=c^2
49 + 4 = c^2
53 = c^2
sqrt:53

Answer:
x = -7/11, y = -14/11
Step-by-step explanation:
2x = y ------- (1)
7y = -7+3x -------- (2)
from (1)
2x = y
y = 2x ------- (3)
substitute (3) into (2)
7y = -7+3x
7(2x) = -7+3x
14x = -7+3x
14x-3x = -7
11x = -7
x = -7/11
substitute x = -7/11 into (3)
y = 2x
y = 2(-7/11)
y = -14/11
x = -7/11, y = -14/11
