The answer is 45 inches all you have to do is add 18.t and 26.5 since its perimeter and perimeter means to add
No they are not equal because if x=10 then the equation would look like this 30+6=10+6
36=16
And that is not correct
−10x + 1 + 7x = 37
combine like terms
-3x + 1 = 37
subtract 1 from both sides
-3x = 36
divide both sides by (-3)
x = - 12
Answer
x = - 12

Answer:
The amount of chamomile tea that has to be used in order to obtain a mixture that costs $14.32 per pound is 8.997 pounds
Step-by-step explanation:
In order to find out the amount of chamomile tea that must be used in the mixture to obtain a 14.32 $ per pound, we can use an weighted average where the price points for each kind of tea are the weights and "c" is the amount of chamomile that we have to use in order to obtain the price per pound that we want. So we have:
(18.5*c + 12.23*18)/(c + 18) = 14.32
18.5*c + 220.14 = 14.32*(c+18)
18.5*c + 220.14 = 14.32*c + 257.76
18.5*c - 14.32*c = 257.75 - 220.14
4.18*c = 37.61
c = 8.997 lb
