William found some shells. he lost 3 of them then there were 6 left. how many shells did he find?

The system of equations graphed below has how many solutions? y = 2x + 2

For what value of x does 4x = (1/8) x + 5?

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125
