Answer:
x= 2 5/6
Step-by-step explanation:
1/3= 2/6
2 1/2= 2 3/6
2/6+ 2 3/6= 2 5/6
Hope this helps! :)
Answer: n = 130
Step-by-step explanation:
The sequence is an Arithmetic progression ( AP )
The last term of the sequence is (L) is 394 with the formula
L = a + ( n- 1 )d . From the sequence, a = 7, d ( common difference ) = 3 and L ( last term ) = 394, and n = ?
Put those values in the formula above and solve for n.
a + ( n - 1 )d = L
7 + ( n - 1 ) x 3 = 394
7 + 3n - 3 = 394
4 + 3n = 394
3n = 394 - 4
3n = 390
n = 130
You can use prime factorization to figure this out.

Answer:
1. I, II,
Step-by-step explanation:
<em>I. Diagonals are perpendicular bisectors of each other </em>
Yes, because 4 sides are congruent so it makes the two diagonals perpendicular bisectors
<em>II. Diagonals bisect the angles from which they are drawn </em>
Yes, That is the property of the diagonal!
<em> III. Diagonals form four congruent isosceles right triangles. </em>
No, only two pairs of right triangles are congruent and sometime the side of each pair are different to each other.
Hence, we choose I and II
