(W - 4/9)(-2/3) = -4/5......divide both sides by -2/3
W - 4/9 = (-4/5) / (-2/3)
W - 4/9 = -4/5 * -3/2
W - 4/9 = 6/5....add 4/9 to both sides
W = 6/5 + 4/9
W = 54/45 + 20/45
W = 74/45 or 1 29/45
40t = 60(t-1)
distribute the right side
40t = 60t-60
subtract 60t from each side
-20t =-60
divide both sides by -20
t = -60 / -20 = 3

<span>1/2(7x + 48) = 3.5x + 24
</span>
<span>-(1/2x - 3) + 4(x + 5) = -0.5x + 3 + 4x + 20 = 3.5x + 23
So yes, </span><span>1/2(7x + 48) will always have higher value.
</span>
<span>new expression that always has a greater value than both of these expressions is: 3.5x + 25</span>
It is A and C because for A it go like 15, 5, 10
C got go like 30, 15, 5
Answer: concave hexagon
Step-by-step explanation:
Concave polygons have diagonals that are outside of the polygon. In a convex polygon, all the diagonals are inside, so we know it can’t be convex.
Hexagons have six sides, while pentagons have five sides, so it must be a hexagon.
So, concave hexagon is correct or choice 3
