If the temperature was 3 degrees Fahrenheit at Midnight, and it dropped 7 degrees during the next hour, then the temperature at 1 A.M. would be -4 degrees Fahrenheit. This is true because 3 - 7 = -4.
So, the answer to this question is that the temperature was -4 degrees Fahrenheit at 1 A.M.
Answer:
x=0 y=3
Step-by-step explanation:
Answer:
x= -1/3
y= -3 1/3
Step-by-step explanation:
Make both of them into y=Mx+b form
y=-x-3
y=(-x-7)/2
Substitute the x-3 in the first equation for the y in the second one.
x-3=(-x-7)/2
2x-6=-x-7
3x=-1
x=-1/3
Now that we have x, we can solve for y.
y=-x-3
y=-1/3-3
y=-3 1/3
Answer:
In 37 years the population will be 125,012
Step-by-step explanation:
Giving the following information:
Initial population (PV)= 67,000
Growth rate (g)= 1.7%= 0.017
Number of years (n)= 37
<u>First, we will establish the future value (FV) formula:</u>
FV= PV*(1+i)^n
FV= 67,000*(1.017^n)
<u>Now, for 37 years:</u>
FV= 67,000*(1.017^37)
FV= 125,012
In 37 years the population will be 125,012
The variable x represent the length of rectangle.
<h3>What is Algebra?</h3>
A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Perimeter= 64 units
let the length be x.
So, width = x - 3
So, Perimeter of rectangle = 2 ( l + w)
64 = 2( x+ x -3)
32 = 2x -3
29= 2x
x= 29/2
Hence, the variable x represent the length of rectangle.
