Answer:
20 people
Step-by-step explanation:
Let x be the number of people initially. We can find the amount each of them has to pay at first
2 / x
But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means
From here we can perform cross multiplication
Multiply both sides by 10x:
x = 20 or x = -10
Since x can only be positive we will pick x = 20
Answer:
50
Step-by-step explanation:
Answer:
Wait..Where's the question?
Step-by-step explanation:
20 = × + 2 (2x-5)
20 = x + 4x - 10
20 = 5x - 10 add 10 to both sides
30 = 5x divide both sides by 5
6 = x
1 side is 6 the other 2 sides are 7
<h2>Answer</h2>
Coordinates of point B':
B' = (-1, -4)
<h2>Explanation</h2>
To reflect a point or a figure across the x-axis we use the rule:
→
In other words, we multiply the y-coordinate of our points by -1, while leaving the original x-coordinate as it is.
Let's apply the rule to every point of our triangle :
A = (2, 1)
A' = (2, 1*-1) = (2, -1)
B = (-1, 4)
B' = (-1, 4*-1) = (-1, -4)
C = (3, 7)
C' = (3, 7*-1) = (3, -7)
