The numbers for the first eight beads that are white are; 1, 5, 9, 13, 17, 21, 25, 29

<h3>Arithmetic Sequence</h3>

We are told that she strings in this order;

  • 1 white
  • 3 blue
  • 1 white bead

Now, after the first white bead, the next white bead is the 5th bead in total.

This means the difference in interval between white beads is; 5 - 1 = 4 beads

Thus, the numbers for the first eight beads that are white are;

1, (1 + 4), (1 + 4 + 4), (1 + 4 + 4 + 4).....

Thus, we have;

1, 5, 9, 13, 17, 21, 25, 29

The monthly rent of Marilyn's house went from $500 to $400, if p is the percent decrease in the rent, which proportion can be us
faust18 [17]
For this case we can use the following rule of three:
 $ 500 ---------> 100%
 $ 400 ---------> x
 Clearing x we have:
 x = (400/500) * (100) = 80%
 Therefore, the percentage of decrease in the rent is:
 p = 100-x
 p = 100-80
 p = 80%
 Answer:
 
a proportion can be used to calculate p is:
 
p = 100 - ((400/500) * (100))

Answer:

x=3 and y= 4 / 3 (Fraction)

Step-by-step explanation:

Substitute x for 6y-5.

2(6y−5)−3y=2

Add 6y and 3y, and multiply 5 by 2/Simplify the equation.

9y−10=2

Add  10 to both sides, and then divide each side by 9.

9y−10+10=2+10

9y / 9 = 12 / 9

y = 4/3.

Repeat the process but replace y with 4/3!
