Which of the following expressions are equivalent? Explain. A= 10y + 5 B= 15y C= 5(2y + 1)

(A and B, B and C, A and C)

b and c

Step-by-step explanation:

15y= 5y(2y+1)

15y= 10y+5

15y= 15y

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
