For 2, work backwards. 93.34 divided by 18.69 equals what? That’s your E.
3, use multiplication. 4.30 times 8.60 equals your D.
4, you just do as the problem says.
5, you do the same as number 2.
6, you do the same as 3.
For the word problem, say how someone starts off with 51.15 and has to give that something to 5 people.

Answer:
y = 2·3^x
Step-by-step explanation:
The shape of the graph appears exponential. The horizontal asymptote appears to be y=0, so there is no vertical offset. The y-intercept seems to be 2 (we can't really read the numbers), and the y-value seems to increase by a factor of 3 for each additional unit of x.
The multiplier is 2, and the base of the exponential factor is 3. That gives us ...
y = 2(3^x)
Answer:
Density = 9 dolphins / mi^2 This is the result.
Step-by-step explanation:
Number of dolphins = 175
Radius = 2.5 mi
1. - Calculate the area
Area = pi* r^2
Area = 3.14*2.5^2
Area = 3.14*6.25
Area = 19.625 mi^2
2. - Calculate the density
density = dolphins/mi^2
- Substitution
density = 175 / 19.625
Result
density = 8.9 dolphins/mi^2
Rounding to the nearest whole number
Density = 9 dolphins / mi^2
according to the topic
5000+1400+1700+2200-5000×80%+1200
=55300-4000+1200
=$52500
Thus we choose option B
B.$52,500
See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
