-7n-15≤21. find n
❖ Add 15 to both sides:-
-7n≤21+15
-7n≤36
❖ Now divide by -7 on both sides:-
n≥-5.14 or
n≥-5
The inequality sign changed because we divided both sides by a negative number.
<h3>Good luck.</h3>

Answer:
When we think of World War I, images of the bloody, muddy Western Front are generally what come to mind. Scenes of frightened young men standing in knee-deep mud, awaiting the call to go "over the top", facing machine guns, barbed wire, mortars, bayonets, hand-to-hand battles, and more. We also think of the frustrations of all involved: the seemingly simple goal, the incomprehensible difficulty of just moving forward, and the staggering numbers of men killed. The stalemate on the Western Front lasted for four years, forcing the advancement of new technologies, bleeding the resources of the belligerent nations, and destroying the surrounding countryside. I've gathered photographs of the Great War from dozens of collections, some digitized for the first time, to try to tell the story of the conflict, those caught up in it, and how much it affected the world. This entry is part 2 of a 10-part series on World War I. This installment focuses on Early Years on the front, part II will focus more on the final year of trench warfare.

Step-by-step explanation:
Answer:
- area: 240 ft^2
- bases: 20 ft, 10 ft
- height: 16 ft
Step-by-step explanation:
Apparently, 4/5 of a gallon is used, so covers ...
(4/5)(300 ft^2) = 240 ft^2
The area of the trapezoid is 240 square feet.
__
The short base of the trapezoid is half the length of the longer base, so is ...
(1/2)(20 ft) = 10 ft
The lengths of the bases are 20 ft and 10 ft.
__
The area formula for the trapezoid is ...
A = (1/2)(b1 +b2)h
Filling in the numbers we know, we can find h.
240 = (1/2)(20 +10)h
240 = 15h . . . . . simplify
16 = h . . . . . . . . . divide by 15
The height of the trapezoid is 16 feet.
She used 5.8 pints of white paint.
8.3 (all paint) - 2.5 (blue paint) = 5.8 (white paint)
