(3x + 5) + (2x + 3)

5x + 15

6x + 8

5x + 8

6x + 15

5x +8

Step-by-step explanation:

add the common ones like 3x and 2x and 5 and 3 and when you only see that one of them had an x leave it alone and don't add them.

(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

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
