Answer:

fx) = $3x+4$

1. step:

solve the bracket

fx) = 3( $x$ - 1) 2 + 5

$fx) = 3x-1+2+5$

2. step:

On a certain hot summer's day, 477 people used the public swimming pool. The daily prices are 1.50 for children and 2.25 for ad

Akimi4 [234]

Answer:

212 children, and 265 adults

Step-by-step explanation:

To find the number of children and adults, we can set up a systems of equations.

x= number of children

y= number of adults

Equation 1: Price

1.50x+2.25y=914.25

Equation 2: Total number of people

x+y=477

Now, let's solve the equation using substitution.

Rearrange the second equation to solve for one variable.

x+y=477

x=477-y

Now plug x equals into the first equation, and solve for y.

1.50x+2.25y=914.25

1.50(477-y)+2.25y=914.25

715.5-1.50y+2.25y=914.25

715.5+0.75y=914.25

0.75y=198.75

y=265

We just solved for the number of adults. Now let's plug y equals into the second equation to find the number of children.

x+y=477

x+265=477

x=212

Thomas arrived at the library at 11:45 AMHe left 1 hour 40 minutes laterAt what time did Thomas leave the library?

andre [41]

Answer:

At 1:25 P.M.

Step-by-step explanation:

Thomas arrived at the library at 11:45 AM and he left 1 hour 40 minutes later.

So, 1 hour 40 minutes is equivalent to (60 + 40) = 100 minutes.

Now, after 15 minutes, the time will be 12 P.M.

So, remaining (100 - 15) = 85 minutes i.e. 1 hour and 25 minutes the time will be 1:25 P.M.

Therefore, Thomas leaves the library at 1:25 P.M. (Answer)
