Samantha donated 5 T-shirts to charity and has 16 left. Which equation could be used to find x, the number of T-shirts Samantha had originally? A. x + 16 = -5
B. x - 5 = -16
C. x + 5 = 16
D. x - 16 = 5

It would be D.

Step-by-step explanation:

It would be D. because if, say, x was a 5, 5-16=5, whereas all the other answers have it in the wrong order or have an addition instead of a subtraction. Hope this helps :)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
