2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47
<u>Explanation</u>
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts.
In this case we are going to write two different addition facts and two different subtraction facts as follows:
2.47,9.57,and 7.1
<em><u>Addition facts</u></em>
2.47 + 7.1 = 9.57
7.1 + 2.47 = 9.57
<em><u>Subtraction</u></em>
9.57 - 2.47 = 7.1
9.57 - 7.1 = 2.47

Answer:
8+16+2= 24 legs on ground
Step-by-step explanation:
10x+y = 10y+x +36
x+y=14
9x-9y=36
x-y=4
x= 14-y
14-2y==4
10=2y
y=5
x=9
21, 15, 30
a+b+c=66
c=2b; a=b+6
(b+6)+b+(2b)=66
-6 -6
(b)+b+(2b)=60
2b+2b=60
4b =60
(1/4) 4b = (1/4)60
b= 15, which is the second number
