the answer is yes when you add the same number to each side the inequality is still true. If u subtract then the inequality would not be true because you are taking away from both of the sides which will make the answer smaller. GOT IT ???
Answer:
x = -6
Step-by-step explanation:
-5x+1=31
- Subtract 1 from both sides of the equation.
-5x = 30
x = -6
Answer:
see explanation
Step-by-step explanation:
73.
18 = 3x
(divide both sides by 3 )
6 = x
( multiply both sides by
)
6
= 3x [
×
= 3 ]
divide both sides by 3
x = 2
74.
24 = 2x
( divide both sides by 2 )
12 = x
( multiply both sides by
)
12
= 2x ( divide both sides by 2 )
x = 6
75.
9
× x = 18
( divide both sides by 9
)
x = 2
76.
2 = x ×
( multiply both sides by
)
2
= 4x ( divide both sides by 4 )
x = 
Answer:
y = 4/5x

Her ya go!
Answer:
x = 50
Step-by-step explanation:
In a polygon, the angles add up to 360°:
x + 10 + 2x + 3x + x = 360
7x + 10 = 360
7x = 350
x = 50
