What is the length of a rectangle with width 10in. and area 45 in.

The length is 4.5 in. for the rectangle.

You can find the length by dividing the area (45 in.) by the width (10 in.).  That will give you the length of 4.5 in.  You can do this because the formula for the area of a rectangle is L*W=A.   So  A/W=L

step-by-step explanation:

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
