Answer:
Step-by-step explanation:
This is exponential, of the form
where a is the initial amount and b is the growth/decay rate. If Ginny begins the study with 1200 frogs in the population, our a value is 1200.
If the population is decreasing 3% per year, it is decreasing 100% - 3% = 97% which, as a decimal, is .97. Our exponential function, then, is
The inequality is x + 5274 ≥ 10,000.
The total number of steps I have to take to reach my goal is 4726.
<h3>How many more steps do I have to take?</h3>
Here are inequality signs and what they mean:
- > means greater than
- < means less than
- ≥ means greater than or equal to
- ≤ less than or equal to
Number of steps I have to take + number of steps I have taken ≥Total steps
X + 5274 + x ≥ 10,000
x ≥ 10,000 - 5274
x ≥ 4726

Answer:
x=9
Step-by-step explanation:
We can use similar triangles and ratios. Put the small triangle side over the large triangle side.
9cm 3x -20
---------- = ---------------- We need to add the sides to get to the larger triangle
72+9 cm 3x-20 + 56
We can cross multiply to solve
9 * (3x-20+56) = (72+9) * (3x-20)
Simplify
9*(3x+36) = 81*(3x-20)
Distribute
27x +324 = 243x -1620
Subtract 27x from each side
27x-27x +324 = 243x-27x -1620
324 = 216x-1620
Add 1620 to each side
324+1620 = 216x
1944 = 216x
Divide each side by 216
1944/216 = 216x/216
9=x
