Colleen divided integer a by -5 and got 6. then she divided 6 by integer b and got -3. find the quotient of integer a and integer b

1. Find out interger A and B

       A÷(-5)=6        A has to be a negative number (neg×neg=pos)

       What divided by 5 equals 6? 30

       So, therefore, -30÷(-5)=6        A=(-30)

         6÷B=(-3)        B is negative (pos×neg=neg)

        6÷(-2)=(-3)     So therefore, B= -2

2. Find quotient of interger A and B

    (-30)÷(-2)=15

The answer is 15!

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.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
