47/5=9.40
9*5=45
47/5= 9 2/5
Equation: 17 + x = 23
To solve this you would do 23 - 17 to get x
x = 6
To calculate slope; rise/run
Triangle ABC: run-1 rise-5 slope-5
5 rise/ 1 run (5/1)=5
Triangle DEF: run-2 rise 10 slope-5
10 rise/ 2 run (10/2)=5
B. They are equal because the two triangles are similar
