Solve –3 + c = –8.<br> A. -5 B. 11 C. 5 D.-11
sergey [27]

Answer:

The answer is A. -5

Step-by-step explanation:

Write out the equation:

-3 + c = -8           Add 3 on both sides to isolate the varible on one side

       c =  -5         -8 plus 3 is -5

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <u><em>ONLY </em></u>one side of the equation.

Find the value of x.
Novay_Z [31]

Answer:

x = 50°

Step-by-step explanation:

Angles in a quadrilateral add to 360°

First work out the interior missing angle

360° - ( 40° + 80° + 110° ) = 130°

Angles on a straight line add to 180° so

180° - 130° = 50°
