What number should be added to both sides of the following equation to solve for g?

g - 18 1/3 = 25

Add 9 to both sides of the equation.
Subtract 9 from both sides of the equation.
Subtract 13 from both sides of the equation.
Add 9 to the left side of the equation.

Answers

Answer:

43 1/3

Step-by-step explanation: Not sure what that second part it but for that equation it is 43 1/3 because you need to isolate the variable by adding the 18 1/3 to the 25 and whatever that equals is your answer so I added

g-18 1/3=25

18 1/3+25

g= 43 1/3

^ see it says g= ___ and that is what g equals

PLEASE HELP PROBLEM IN PHOTO!

Answers

Answer: Should be 130

Step-by-step explanation:

A is 80 180-80 is 100. Since it’s an isosceles you can divide by 2 and the two angles would be the same. 100/2 is 50 because two remote interior angles is equal to the exterior angle, 50+80 is 130, d is 130

Answer:

Angle D is 130 degrees

Step-by-step explanation:

180-80=50

Angles b and c are the same and will both be 50 degrees.

The angle of a straight line is 180 degrees.

Since angle c is 50 degrees, then the other angle (d) will have to be 130, so that together the total of the two is 180 degrees.
