x²+4x-30=0


Answer:
6.7 seconds
Step-by-step explanation:
Juan= Paul-0.4
Paul=Terry+1.3
We can substitute Terry+1.3 for Paul since they are equal
juan=(Terry-0.4)+1.3
terry=5.8
juan=(5.8-0.4)+1.3
juan=6.7
This should be right! $5,000 + $1,000x
More are so a 30-40% chance they would mostly talk about how they are to costumers
90. The original cost of a camera of a camera is 150 dollars, Now it decreased into 65 dollars.
Let’s solve for the percent of decreased in the price of the camera.
=> 150 = 100%
=> 65 / 150 = .43
=> .43 * 100% = 43%, 65 = 43% of the amount
=> 100% - 43% = 57%
Thus, the price of the camera decreased for about 57% of the original price and now only costs 43% of the original price.
