9x + 6 + 2(5x-3) + 5y +14
9x + 6 + 10x - 6 + 5y +14
19x + 5y + 14
19x = -5y -14
x = -5y/19 - 14/19
There were about 18 people younger than 15 in the park.
Answer:
Step-by-step explanation:
The similar triangles are shown in the attached photo.
Triangle ABC is similar to triangle XZY. Therefore,
AB/XZ = BC/ZY = AC/XY
From the dimensions given,
(x-8)/45 = (2x - 8)/24
Cross multiplying,
24(x-8) = 45(2x - 8)
24x - 192 = 90x - 360
Collecting like terms and making the terms containing the variable, x be on the left hand side and the constants be on the right hand side,
24x - 90x = -360+92
-66x = -268
x = 268/66
x = 4.06
x = 4
What is the median of the data set shown?34, 86, 12, 56, 21, 98, 72, 34, 21, 34, 45, 23, 97, 44

Answer: The median of the data is 34
Step-by-step explanation: the reason why it is 34 is because when your dealing with medians you want to put down the number that you see the most of for example you see 34 three times so the number you see the most is 34 so the answer is 34
Answer:
Slope is equal to the change in y over the change in x , or rise over run.
m=change in y/ change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope.
m=0−(2)/9−(5)
Simplify.
m=−12
