Believe it or not, this is the second version of Q is very similar to the first, even though it doesn't really look like it. We can represent the second version as a * (1 + r)^t
See the similarity between this and the first version? Thus, we can represent what is given in the problem as:
Q = a * b^t = a * (1 + r)^t
Thus, b = 1 + r. Since b = 0.8, we can find r.
0.8 = 1 + r
r = -0.2, or r = -20%.
Answer:
x < -3
Step-by-step explanation:
1. To put this inequality on a number line, we first must solve it.
Step 1: Subtract 15 from both sides.
Step 2: Divide both sides by 5.
2. Now that we know x < -3, let's graph it!
- Since it's less than, we make the number line point to the left, and we make the circle open.
Answer:
10:6=10*7:6*7
10:6=70:42
70+42=112
White ball 70 and striped balls 42
