Mya takes a drive from a springboard at a swimming pool. The board is 3 1/2 feet above the surface of the water. The total length of her dive is 8 3/4 feet. How far below the surface of the water is mya at the end of the dive

dive below = 5 1/4 ft

Step-by-step explanation:

Dive above water + dive below water = total dive

We know the dive above water is 3 1/2 ft

The total length of the dive is 8 3/4 ft

Substitute in what we know

3 1/2 + dive below = 8 3/4

get a common denominator of 4

3 1/2*2/2 + dive below = 8 3/4

3 2/4 + dive below = 8 3/4

Subtract 3 2/4 from each side

3 2/4 - 3 2/4 + dive below = 8 3/4 - 3 2/4

dive below = 5 1/4 ft
