Hampton ate 7 slices of fruit at lunch. after dinner, he ate
some more. he ate a total of 15 slices of fruit.

If you are trying to find the answer its 8 obviously, but if you are looking for an  equation to find the answer it would be 15 - 7 = x or 7 + x = 15.

Step-by-step explanation:

282 6/7 cm^2

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
