Luicia tried to solve the system 2x +2y =14 x-2y=-2

(x, y) = (-1/4, -3/4)

Step-by-step explanation:

1. Write as a system

2x + 2y = 14x - 2y = -2

2. Eliminate one variable by adding the equations

2x + 2y = -2

14 x - 2y = -2

3. Divide both sides by 16

16x = -4

4. Substitute the value of x into the equation.

x = -1/4

5. Solve the equation

2(-1/4) + 2y = -2

6. A possible solution is

y = -3/4

7. Check the solution

(x, y) = (-1/4, -3/4)

8. Simplify the expression

2(-1/4) + 2(-3/4) = 14(1/4) - 2(-3/4) = -2

9. The ordered pair is a solution

-2 = -2 = -2

10. (x, y) = (-1/4, -3/4)

answer: a) 56% women

b)44% men

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.
