Answer:
Step-by-step explanation:
Hi there!
Let the smaller number be x and the larger number be 2x+1.
According to the question,
The sum of the numbers is 20 less than three
times the larger.
i.e x + (2x+1)= 3*(2x+1) - 20
or, x + 2x +1 = 6x + 3 -20
or, 3x + 1 = 6x - 17
or, 3x = 18
or x= 18/3
x = 6
And 2x+1 = 2*6+1 = 13.
Therefore the smaller number is 6 and larger number is 13.
Hope it helps!

Step-by-step explanation:
count up 5, count left 7
negative slope so negative 5/7
THIS IS THE COMPLETE QUESTION BELOW
The demand equation for a product is p=90000/400+3x where p is the price (in dollars) and x is the number of units (in thousands). Find the average price p on the interval 40 ≤ x ≤ 50.
Answer
$168.27
Step by step Explanation
Given p=90000/400+3x
With the limits of 40 to 50
Then we need the integral in the form below to find the average price
1/(g-d)∫ⁿₐf(x)dx
Where n= 40 and a= 50, then if we substitute p and the limits then we integrate
1/(50-40)∫⁵⁰₄₀(90000/400+3x)
1/10∫⁵⁰₄₀(90000/400+3x)
If we perform some factorization we have
90000/(10)(3)∫3dx/(400+3x)
3000[ln400+3x]₄₀⁵⁰
Then let substitute the upper and lower limits we have
3000[ln400+3(50)]-ln[400+3(40]
30000[ln550-ln520]
3000[6.3099×6.254]
3000[0.056]
=168.27
the average price p on the interval 40 ≤ x ≤ 50 is
=$168.27
Answer:
What is the aswer?
Step-by-step explanation:
C=8πab
Divide both sides by 8πb
c/(8πb) = a
