That makes no sense I think you’re missing some words but the answer might be $7.5 per hour bc 21-6 is 15 and that divided by 2 s 7.5
Just add 3 to both sides
x = 7
1 yard=36 inches
9 times 1=9
multiply both sides by 9
9 times 1 yard=9 times 36 inches
9 yard=324 inches
5 because 25 divided by 5 is 5
6.4 rounded to the nearest whole number is 6
