The answer is 130. you do the math in the parentheses first then you add those two numbers together

The county fair chargers $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75 at

zlopas [31]

let's see what to do buddy....

The county fair charges 1.25 $ per ticket:

Stop :

So if Jermain has bought 25 tickets, he has already spent that much money which equal :

$25 \times 1.25 = 25 \times 125 \times {10}^{ - 2} = 25 \times (100 + 25) \times {10}^{ - 2} \\ = (2500 + 625) \times {10}^{ - 2} = 3125 \times {10}^{ - 2} = 31.25$

So jermain spent 31.25 dollors only for the tickets.

But he spent the total of 43.75 $.

Look : 43.75 $ - 31.25 $ = 12.5 $

Where are the 12.5 $ spent ?

Easy ----¢ This is the cost of fair admission.

Due of all those things we have to pay 1.25 $ per ticket and 12.5 $ for fair admission.

A) x as the number of the ride tickets

y as the total cost we should pay

or as the total money we should

spend

$y = 1.25 \: x + 12.5$

iven: C is a point on the perpendicular bisector, l, of AB. Prove: AC = BC Use the drop-down menus to complete the proof. By the

Answer:

See the attached figure for better explanation :

Step-by-step explanation :

1. By the unique line postulate, you can draw only one line segment : BC

Since only one line can be drawn between two distinct points.

2. Using the definition of reflection, reflect BC over l.

To find line segment which reflects BC over l, we will use the definition of reflection.

3. By the definition of reflection, C is the image of itself and A is the image of B.

Definition of reflection says the figure about a line is transformed to form the mirror image. Now, CD is perpendicular bisector of AB so A and B are equidistant from D forming the mirror image of each other.

4. Since reflections preserve length, AC = BC

In Reflection the figure is transformed to form a mirror image, Hence the length will be preserved in case of reflection.
