When using substitution to solve this system of equations, what is the result of the first step?
Answers
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

The Royals softball team won 55 games and lost 25 games. What percent of the games did they lose? Round to the nearest whole percent.
_______% games lost
Answers
Answer:
31% games lost.
Step-by-step explanation:
Given that the Royals softball team won 55 games and lost 25 games, the following calculation must be performed to determine the percentage of games they lost out of the total games played:
55 + 25 = 80
80 = 100
25 = X
(25 x 100) / 80 = X
2,500 / 80 = X
31.25 = X
Thus, rounded to the nearest percentage, the Royals lost 31 percent of their games.

How much money needa to be deposited now into an account to obtain 9,000 in 7 years if the interest rate is 8% per year compounded continuously?
Answers
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
