I believe x is 43.
3x+17+x-9=180 It is 180 because a straight line is 180 degrees
4x+8=180
-8 -8 subtraction property of equality
---------------
4/4x=172/4 division property of equality
x=43 solution
Answer:
The population will be of 2400 in 36 years.
Step-by-step explanation:
The equation for the population of plants after t years follows the following format:
In which P(0) is the initial amount of plants and r is the yearly rate which it increases.
Assuming that the initial population is 300
This means that P(0) = 300.
The doubling time of a population of plants is 12 years.
This means that P(12) = 2*300 = 600.
We use this to find r.
![\sqrt[12]{(1+r)^{12})} = \sqrt[12]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B12%5D%7B%281%2Br%29%5E%7B12%7D%29%7D%20%3D%20%5Csqrt%5B12%5D%7B2%7D)
So
How large will the population be in 36 years
This is P(36)
The population will be of 2400 in 36 years.
Answer:
3/4.
Step-by-step explanation:
36 and 48 have a common factor of 12.
(36 / 12) / (48 / 12)
= 3/4 (answer).
Answer:
The shoes at the other store could be at the most 70.13.
Step-by-step explanation:
In order to find this, we need to set them equal to each other. Start by multiplying the first cost by the amount of the total price you'll be paying.
65.75 * 80%
And the other side would be the amount of the total price being paid times x.
x * 75%
Now set them equal to each other and solve.
65.75 * 80% = x * 75%
52.60 = x * 75%
70.13 = x
Answer:
2/15
Step-by-step explanation:
2/3 - 8/15
Get a common denominator
2/3 *5/5 = 10/15
10/15 - 8/15
2/15
