Answer:
x = 20
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to the exterior angle
x + 2x+10 = 70
Combine like terms
3x+10 = 70
Subtract 10 from each side
3x+10-10 = 70-10
3x = 60
Divide each side by 3
3x/3 = 60/3
x = 20

Answer:
Substitute 7 for a.
Simplify the equation after substituting the value for a.
Verify that a = 7 is correct when the result is a true statement.
Step-by-step explanation:
–9(a – 5) = –18
Distribute
-9a +45 = -18
Subtract 45 from each side
-9a +45-45 = -18-45
-9a = -63
Divide each side by -9
-9a/-9 = -63/-9
a = 7
To check the solution put a =7 back into the original equation
–9(a – 5) = –18
-9(7-5) = -18
Simplify
-9(2) = -18
-18 = 18
This is true so 7 is the solution
