the answer is 12 because if you look at the position of the y axis when x equals 2 then look at the y value when x equals 4 you will get the 2 numbers 4 and 16 now subtract 16 by 4 and you get 12.
Hello. To answer this questions, we need to remember some properties about fractions and equivalences.
Starting by the question 9:
Call the population 5 years ago by P. If the population has decreased 12000 in these 5 years and this represents a decrease of 3%, so it means the new population is 0.97P.
With this, we can make the following equation:
P - 12000 = 0.97P
Subtract 0.97P and sum 12000 in both sides of the equation
0.03P = 12000
Divide both sides of the equation by a factor of 0.03
P = 3600000
First find the rate of each painter given the time it takes for them each to complete the job.
Eric rate: 1/14 of the job per minute
Brother: 1/35 of the job per minute
Together: 1/14+1/35 = 7/70 = 1/10 of the job per minute
This means that the job will be completed in 10 minutes.
answer: 10 minutes
$1.30. You can take the two statements and make them into equations. First set X equal to the number of dimes and Y equal to the number of quarters. Next set up your equations. the first .1X times .25Y=4.55 and X=Y. Next use substitution to solve for X, and you get 13. Next multiply 13 times .1 to get 1.3 which is in dollars.
Yes indeed ! You've come to the right place.
You said that 5k = -84.05
Now, watch closely:
Divide each side by 5 : k = -16.81 .
