Solve for “x” x+2 1/2=10.

x = 7.5

Step-by-step explanation:

x + 2 1/2 = 10

Subtraction Property of Equality

x = 7 1/2 as a mixed number = 15/2 as an improper fraction = 7.5 in decimal form

I usually prefer decimal form

answer: i believe c. is the answer sorry if i am wrong

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
