Answer:
x = 4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
20x+5−0=5x+(32.5)(2)
20x+5+0=5x+65
(20x)+(5+0)=5x+65(Combine Like Terms)
20x+5=5x+65
20x+5=5x+65
Step 2: Subtract 5x from both sides.
20x+5−5x=5x+65−5x
15x+5=65
Step 3: Subtract 5 from both sides.
15x+5−5=65−5
15x=60
Step 4: Divide both sides by 15.
15x
15
=
60
15
x=4

You have to convert the pound to ounces and ounces to pounds
Let x represent the length of the shortest side. Then the longest side is
... 2x -7 . . . . . . 7 ft shorter than twice the shortest side
and the 3rd side is
... x +2 . . . . . . 2 ft longer than the shortest side.
The perimeter is the sum of the side lengths,
... x + (2x -7) + (x +2) = 59 . . . . . the given perimeter length
... 4x -5 = 59 . . . . collect terms
... 4x = 64 . . . . . . add 5
... x = 16 . . . . . . . . divide by 4
Then the other sides are
... 2×16 - 7 = 25 . . . . . longest side
... 16 +2 = 18 . . . . . . . . third side
The side lengths are 16 ft, 18 ft, and 25 ft.
- Average Rate of Change/Slope Formula:
So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:
From here we can solve for y. Firstly, solve the subtraction:
Next, multiply both sides by 4:
Next, subtact both sides by 71:
Lastly, multiply both sides by -1, and <u>your final answer will be 
, or A.</u>
The line of best fit , also called a trendline or a linear regression, is a straight line that best illustrates the overall picture of what the collected data is showing. It helps us to see if there is a relationship or correlation between the two factors being studied. This trendline helps us to predict future events relating to the data being studied. Hope this helped!
