D-10-2d+7 = 8 + d- 10 -3d
d-2d-10+7 = 8-10 +d -3d
-d-3=-2-2d
-d+2d=3-2
d=1
Final answer: C. d=1

Step-by-step explanation:
Becky went scuba diving. The inequality statement compares the magnitude of two depths that she reached.
1-28] > 1-3
What does the inequality statement show?
Select from the drop-down menus to correctly complete the statement.
-28 is greater
than-3, but 28 m below sea level is a greater
depth than 3 m below sea level.
Step-by-step explanation:
the outer left side is also 50 ft.
in inner (upper) left side is also 13 ft.
the bottom line is 10+20+11 = 41 ft
this is all possible because all the angles are clearly right angles (90°).
so, the perimeter is
2×(10+20+11) + 2×50 + 2×13 = 82 + 100 + 26 = 208 ft
