#10. Maddy had twice as many stamps as Simon. After Maddy sold 60 stamps, Sinom had twice as many stamps as Maddy. How many more stamps did Maddy have than Simon in the beginning?

Answers

Answer:

8. $114

10. 60 stamps

Step-by-step explanation:

Let Dylan have d, Mike have m, and Jeremy have j

3 of them have 171, so we can write:

1. $d + m + j = 171$

Mike has twice as Dylan, so we can write:

2. m = 2d

Jeremy had three times as Mike, so:

3. j = 3m

We can write equation 3 as m = j/3

Also, if we put this into equation 2, we have:

j/3=2d

d=j/6

Now we have d and m in terms of j. We put it into equation 1 and solve for j:

$(j)/(6) + (j)/(3) + j = 171\n(3j+6j+18j)/(18)=171\n(27j)/(18)=171\n27j=18*171\n27j=3078\nj=(3078)/(27)\nj=114$

Jaime has $114

10.

amount of stamps Maddy has is m and amount Simon has is s

Maddy had twice as many stamps as Simon:

m = 2s

Also

After Maddy sold 60 stamps, Sinom had twice as many stamps as Maddy:

s+60=2(m-60)

We put the first equation in the second and solve for s:

s+60=2(m-60)

s+60=2(2s-60)

s+60=4s-120

180=3s

s=60

THus, m = 2(60) = 120

So maddy had 120 - 60 = 60 more stamps than Simon

Find the 9th term

Answers

Answer:

The ninth term would 0.25.

Step-by-step explanation:

The pattern happening here is that the number is being divided by 2.

So, continuing the pattern, continue dividing by 2.

8÷2= 4 ----> 5th term

4÷2= 2 ----> 6th term

2÷2= 1 ----> 7th term

1÷2= 0.5 ----> 8th term

0.5÷2= 0,25 ---> 9th term

Which one is smaller; 0.0175, 0.65, or 0.876

Answers

0.0175, 0.65, 0.876

The smallest among these is 0.0175

after the decimal point, we see that in 0.0175 the tenth value is 0
in 0.65 the tenth value is 6
and in 0.876 the tenth value is 8

So from smallest to biggest(if needed)

0.0175, 0.65, 0.876

Factor the sum of terms as a product of the GCF and a sum of 20 + 64
