Step-by-step explanation:
(given)
Let us consider :
=
=
=
=
=
Now, by substituting the above considerations in the above equation, we get:
where,
1
then it follows
n = 20
r = 4
then no. of solutions for the eqn =
=
= 10626
Answer :
no. of solutions for the eqn 10626
Answer:
The Answer is J because 1 1/2 or 1.5 times itself equals 2 1/4 or 2.25
Ok so
x - the smallest
The other 4 are : x+1, x+2, x+3, x+4
We know that sum is 120
So
x+x+1+x+2+x+3+x+4=120
Combine like terms
5x+10=120
Subtract 10 on both sides
5x=120-10
5x=110
Divide by 5 on both sides
X=22
The third number is x+2 = 22+2=24
