Since the common difference is 6, we can assume that the sequence is arithmetic, with rule
T(n)=6n+5 where T(1)=11
T(9)=6(9)+5=59
Answer:
A square field has a perimeter if 3.6km what is the length of one side in metres
Step-by-step explanation:
A square field has a perimeter if 3.6km what is the length of one side in metres
(8,12)(14,3)
Use midpoint formula
(X1+x2/2, y1+y2/2)
Substitute with your points
(8+14/2, 12+3/2)
Solve each
(22/2,15/2)
Cancel common factor 2
(2×(4+7)/2(1),15/2)
Simplify
(4+7/1,15/2)
This is your midpoint
(11, 15/2)
Answer:
Step-by-step explanation:
let x be the numerator of the rational number then 2x is the denominator
original fraction = 
subtracting 3 from numerator and adding 7 to denominator , gives
= 
( cross- multiply )
5(x - 3) = 2(2x + 7) ← distribute parenthesis on both sides )
5x - 15 = 4x + 14 ( subtract 4x from both sides )
x - 15 = 14 ( add 15 to both sides )
x = 29
rational number =
3x+4=x+2
2x+4=2
2x=-2
-2/2
X=-1
Y=-1+2
Y= 1
Solution= (-1,1)
