Answer:

D y= 81

Step-by-step explanation:

Since the triangles are similar, the ratios of similar sides must be equal.

30/54 = 45/ y

We can use cross products

45*54 = 30*y

2430=30y

Divide each side by 30

2430/30 = 30y/30

81 =y

Factor each expression.<br><br> (9) 5a - 25<br><br> (10) 28 - 7x<br><br> (11) 12z + 28 - 7z - 3
Nimfa-mama [501]

Answer:

Step-by-step explanation:

Look for the GCF and then divide every term by the GCF to see what remains

(9) 5a - 25  ( GCF is 5 so take out 5 and divide every term by 5)

     5(a-5)

(10) 28 - 7x     ( GCF is 7 so take out 7 and divide every term by 7)

     7(4-x)

(11) 12z + 28 - 7z - 3=  (combine terms) =

       5x+25( GCF is 5 so take out 5 and divide every term by 5)

        5(x+5)
