Complete Question:

A number decreased by eight is five.

Group of answer choices.

A. C + 8 = 5

C. -8c = 5

B. C - 8 = 5

D. S = 5

B. C - 8 = 5

Step-by-step explanation:

Let the unknown number be C.

Translating the word problem into an algebraic equation, we have:

C - 8 = 5

Simplifying further, we find that;

C = 5 + 8

C = 13

Therefore, the unknown number is 13.

(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

x=0
