the temperature on a summer afternoon is 76°f. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of 8 degrees fahrenheit.
8 + c; 8 + (–76) = 84; 84°f
76 – c; 76 – (–8) = 84; 84°f
8 – c; 8 – (–76) = 68; 68°f
76 + c; 76 + (–8) = 68; 68°f

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
