Answer:
9 9/20
Step-by-step explanation:
4 1/5 * 2 1/4
Change the mixed nubers to improper fractions
4 1/5 = (5*4+1)/5 = 21/5
2 1/4 = (4*2+1) /4 = 9/4
21/5 * 9/4 = 189/20
Now we change it back to a mixed number
20 goes into 189 9 times (20*9 = 180 with 9 left over)
9 9/20
A shape with 10 sides is a decagon.
Answer:
slope is 1
Step-by-step explanation:
5-3/-4--6 = 2/2 = 1
since they are all in the same line you only need to use 2 of the points I'm using (1,-1) and (2,1) next you do (x1,y1) and (x2, y2) which would be (1,2) and (-1, 1) then do y2-y1 / x2-x1 which would be 1/2
