Answer:
G
Step-by-step explanation:
ΔABC has two congruent angles. Therefore, it is an isosceles triangle.
Therefore we have the equation (1) 3x - 5 = y + 12.
All angles of the ΔDBC are congruent. Therefore it is an equilateral triangle.
Therefore we have the equation (2) 3x - 5 = 5y - 4
From (1) and (2) we have the equation:
5y - 4 = y + 12 <em>add 4 to both sides</em>
5y = y + 16 <em>subtract y from both sides</em>
4y = 16 <em>divide both sides by 4</em>
y = 4
Substitute the value of y to (1):
3x - 5 = 4 + 12
3x - 5 = 16 <em>add 5 to both sides</em>
3x = 21 <em>divide both sides by 3</em>
x = 7
<h3>Answer: x = 7 and y = 4</h3>
Jacob received 15.3 pounds of bell peppers.
Answer:
Mean= 13.38
Median= 15
Step-by-step explanation:
The mean can be calculated by getting the sun of the 8 scores and then dividing it by the number of students
Mean= 7 + 18 + 18 + 15 + 17 + 10 + 15 + 7/8
= 107/8
= 13.38
The median can be calculated by first rearranging the numbers from the lowest to the highest and then calculating the average of the two middle numbers
7 , 7, 10, 15, 15, 17, 18, 18
Median = 15+15/2
= 30/2
= 15
Hence the mean is 13.38 and the median is 15
