Step-by-step explanation:
let age of samantha be 3x and age of jason be x.(since samantha is three times as old as jason)
Now,
3x+x=56 (sum of their ages is 56)
or 4x=56
or x=56/4
or x=14
therefore age of samantha=3x=3×14=42
age of jason = x = 14
The answer for the question is y = 3x + 5
Answer:
<h2>A = 20</h2><h2>P = 6√10</h2>
Step-by-step explanation:
The formula of a distance between two points:
A(-3, 0) , B(3, 2)
A(-3, 0), D(-2, -3)
AB = CD and AD = BC
The area of a rectangle:
Substitute:
The perimeter of a rectangle:
Substitute:
The median is the middle-most number. First we need to put the numbers in order from lowest to highest:
81 84 88 94 94 96
The easiest way to find the median is to cross out the first and last number and then continue until you reach the middle.
So cross out 81 and 96:
84 88 94 94 are left.
Cross out 84 and 94:
88 and 94 are left.
Since we are left with 2 different numbers, we need to find the average of them and that’s our median. (88 + 94)/2 = 91
91 is the median.
