It is wrong. When you add 28 to both sides, one gets

j= 10

in baseball, the pither's mound is 6 in. more than 20 yd from home plate . how many feet is this

To find out how many feet the pitcher's mound is from home plate, you need to convert the given distance of 20 yards into feet.

1 yard is equal to 3 feet, so you can multiply 20 yards by 3 to get the equivalent distance in feet:

20 yards * 3 feet/yard = 60 feet

So, 20 yards is equal to 60 feet.

Now, the pitcher's mound is 6 inches more than 60 feet from home plate. Since there are 12 inches in a foot, you can convert the inches into feet:

6 inches * 1 foot/12 inches = 0.5 feet

Therefore, the pitcher's mound is 60 feet + 0.5 feet = 60.5 feet from home plate.
