Answer:
The money each boy had after buying his ticket is <u>$2.50</u>.
Step-by-step explanation:
Given:
Miguel and three of his friends went to the movies. They originally had a total of $40. Each boy had the same amount of money and spent $7.50 on a ticket.
Now, to find the money each boy had after buying his ticket.
Let the money each boy had after buying his ticket be
Total number of boys = 4.
Total money they had = $40.
Money each boy spent = $7.50.
Now, to write an equation:
Now, to solve the equation for getting the money each boy had after buying his ticket:
<em>Subtracting both sides by 30 we get:</em>
<em>Dividing both sides by 4 we get:</em>
Therefore, the money each boy had after buying his ticket is $2.50.
Answer:
<em>B</em>
Step-by-step explanation:
<u>Dilations</u>
Given a point A(x,y) and a scale factor k the dilated image of A, called A' is calculated as A'=(kx,ky), assuming the same scale factor is applied in both axes.
The pentagon ABCDE was dilated to create pentagon A'B'C'D'E'. To find the dilaton rule used, we must find two clear points where the coordinates of both axes can be easily read from the graph.
Point C(-2,0) maps to C'(-5,0). This gives us the scale factor for the x-axis of -5/(-2)= 5/2.
The y-coordinate of E is 2 and the y-coordinate of E' is 5. This gives us the same scale factor for the y-axis of 5/2.
Thus, the rule to dilate the pentagon is:
B
