Let the smaller number be n:
Therefore 1/2 * n(n+1) = 105
n^2 + n = 210
n^2 + n - 210 =0
Use your preferred method to solve the quadratic, I'll factorise this since this is easy to factorise.
Two numbers':
product gives -210
summation gives 1
Therefore (n+15)(n-14)=0
So the smaller number n is either -15 or 14.
Answer:
where is the point?
if it is .3359085 the answer is .3359
if it's 3.359085 the answer is 3.3591
if it's 33.59085 the answer is 33.5909
if it's 335.9085 the answer is 335.9085
if there is no point the answer is 3360000
Step-by-step explanation:
A bag contains 8 yellow marbles and 6 blue marbles. what number of yellow marbles can you add to the bag so that the ratio of yellow to blue marbles is 2:1? YOU HAVE 8 YELLOW MARBLES SO BY ADDING 4 MORE YOU HAVE (8+4)=12.
The answer is x=9 because if you do 3x+-2 that gives you 1 and 1 divided by 9 is 9 and you get that by getting rid of your 6 first and adding it to the 3 from 3(x+1)
