Answer:
c. -8
Step-by-step explanation:
Hello!
0.5 (5 - 7x) = 8 - (4x+6)
2.5 - 3.5x = 8 - 4x + 6
2.5 - 3.5x = 2 - 4x
-3.5x + 4x = 2 - 2.5
0.5x = -0.5
X = -1
Your answer is x = -1. I hope this helps!
So all you do is you divide 2 1/2 by .25 and you get 10 then you know one fourth or 25% of that package is 10 berries so the rest or 30% left over is 30 berries.
Let the width be x. Since the length is 30inches longer than the width, the length is 30 + x.
Area = length x width = (30 + x)(x)
i.e. (30 + x)(x) = 1800 square inches.

x + 60 = 0 or x - 30 = 0
x = -60 or x = 30
but the width cannot be a negative number, hence x = 30inches
i.e. width = 30 inches
length = 30 + 30 = 60 inches.
Answer:
87 2/10 km^2. hope it's helpful
Step-by-step explanation:
area = l X w
= 8 km X 10 9/10 km
= 8 X 109/ 10 km^2
= 872/10 km^2
