Stacey and Jeremy sent out 380 invitations They have received 127 responses. What does q represent in the equation 380- q = 127

the length of a rectangular label is 2.5 cm less than twice the width. the perimeter is 40.6 cm. find the width.
Aleksandr [31]
Let the width be w, then the length is 2w - 2.5.
Perimeter = 2(length + width)
40.6 = 2(2w - 2.5 + w) = 2(3w - 2.5)
3w - 2.5 = 40.6/2 = 20.3
3w = 20.3 + 2.5 = 22.8
w = 22.8/3 = 7.6

Therefore, width is 7.6 cm.
