5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
4) x + x + x = 180°
An equilateral triangle has three sides of equal length. Its interior angles are also equal. Since interior angles of a triangle should sum up to 180°, then each angle is 60°, making each angle congruent with one another.
So if x is equal to one angle and triangles have three angles then,
x + x + x = 180°
or 3x = 180°

<h2><u><em>
Answer:</em></u></h2>
Chickens have 2 legs and cows have 4 legs.
Let x = # of chickens and let y = # of cows.
2x + 4y = 118
x + y = 50
x= 50 - y
2(50 - y) + 4y =118
100 - 2y + 4y = 118
2y = 18
y = 9
x = 41
Answer:
B is symmetric; A is not.
Step-by-step explanation:
Since you did part A, you know that the ends of each box are roughly symmetrically located with respect to the extremes of data in each case. However, the median of the data for School A is decidedly near the right end of the box; whereas the median for School B is in the center of the box.
This last fact gives the box plot for School B a symmetric appearance that is not shared by the plot for School A.
