Answer:
3
Step-by-step explanation:
to find this answer we will then have to do 5 x 2/3
since we our multiplying by a fraction we will then have to change the fraction to a decimal.
2/3 = 0.6
this will then give us the equation of 5 x 0.6
this will give us the sum of 3 jars that had were able to be filled woth marbles.
Let's look at it like this:
5/10+1/5 = (5/10) + (1/5)
5/10 = 0,5
1/5 = 0,2
so it's 5/10 + 1/5 = (5/10) + (1/5) = 0,5 + 0,2 = <u>0,7 </u>
Answer:
Need more infomation to write the equation.
Step-by-step explanation:
I guess you are asking to find the sum of the first 8 terms. If so, then:
Sum = a₁(1-rⁿ)/(1-r), where a₁ is the 1st term, r=common ratio and n=number of terms:
the 1st term a₁ =3
common ratio r = - 2 (since -6/3 = - 2, and 12/-6 = - 2, etc.)
Sum = 3[(1- (-2)⁸]/(1-2) = 3(1- 256)/(1/2)
Sum = -1530
