Plz 30 points! its easy
plz do 4x=2x+2x+5(x-x) but with an explaination
keep in mind this could have one solution, none or many

Step-by-step explanation:

4x=2x+2x+5(x-x)

4x = 4x

here,

x = 0

(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

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
