Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5
Answer:
6 inches
Step-by-step explanation:
The volume of a triangular pyramid can be found using
v=1/3bh
where b is the area of the base, and h is the height
We know the volume is 12, so let's find the area of the base
The area of a triangle can be found using:
a=bh/2
We know the base is 4, and the the height is 3, so we can substitute them in
a=4*3/2
a=12/2
a=6
Now, we can solve for the height
v=1/3bh
Substitute 12 in for v, and 6 in for b
12=1/3(6h)
Multiply both sides by 3
3*12=1/3(6h)*3
36=6h
Divide both sides by 6
h=6
The height is 6 inches
The equation should be y=2x+4
The approximate amount of underdeveloped land in 2013 is A = 15300 X e^-0.07(11).
<h3>How do you determine the future value when there is continuous compounding? </h3>
The formula for calculating future value of an investment when there is continuous compounding is A = P x 
x N
Where:
- P = population in 2002
- r = rate of decrease = 0.07
- n = number of years = 2013 - 2002 = 11 years
A = 15300 X e^-0.07(11)
