Answer:
Step-by-step explanation:
let x = the number of pounds of cheaper coffee.
Since the merchant is mixing this with more expensive coffee, then
x + 60 = the number of pounds of medium priced mixed coffee.
The equation is gotten from this
+ =
(x)($40) + (60)($90) = (x + 60)($70) or
40x + 5400 = 70(x + 60)
Solve that equation and get x = 40
Answer: 40 pounds of $40 coffee.
i hope this helped
Hello from MrBillDoesMath!
Answer:
No solution is possible using odd consecutive integer
Discussion:
Let "n" be the smaller odd integer. Then
n + (n+2) = 9 =>
2n + 2 = 9 =>
2n = 7 => Oops! 2n is an even integer; 7 is odd. NO integer solution exists

I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 (
* 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²
Just do the normal formula but don’t multiply it by pi and then add the pi symbol after.
9 x 5 = 45 and 9 x 50 = 450
