Answer:
b < 10
Step-by-step explanation:
-b - 2 > 8
Add 2 to both sides.
-b > 10
Divide both sides by -1. When dividing by a negative, flip the inequality sign.
b < 10.

Answer:
c + d = 400
0.2c + 0.5d = 156
Step-by-step explanation:
Let
c = number of liters of 20% acid solution
d = number of liters of 50% acid solution.
c + d = 400 (1)
0.2c + 0.5d = 400(0.39)
0.2c + 0.5d = 156 (2)
From (1)
c = 400 - d
Substitute c = 400 - d into (2)
0.2c + 0.5d = 156 (2)
0.2(400 - d) + 0.5d = 156
80 - 0.2d + 0.5d = 156
- 0.2d + 0.5d = 156 - 80
0.3d = 76
d = 76/0.3
d = 253.33 liters
Substitute d = 253.33 into (1)
c + d = 400
c + 253.33 = 400
c = 400 - 253.33
c = 146.67 liters
→Answer:
A. strong positive
→Step-by-step explanation:
Well looking at the following scatterplot we can tell it is not negative only positive.
So we can cross out B. and C.
Looking at the dots and how close they are to creating a line we can decuct answer choice A. Because it is a strong positive.
