A. Is 4, 5, or 6 the solution of the equation c + 8 + 13? b. Solve 9 - x = 2 mentally.
c. The difference between an ostrich's speed and a chicken's speed is 31 miles per hour. An ostrich can run at a speed of 40 miles per hour. Use mental math or the guess, check, and revise strategy to solve the equation 40 - c = 31 tp find the c, the speed a chicken can run.

a.
b.
c.

x+14

step-by-step explanation:

(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
