Answer:

$0.27

Step-by-step explanation:

1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09

     We want to know the ratio of centimeters of streamers to cost of  
     streamers.

2/4 We need to convert meters to centimeters.

      There are 100 centimeters in 1 meter.

      So, if 1 meter of streamers costs $0.09, then 100 centimeters of
      streamers also cost $0.09.

3/4 The ratio centimeters of streamers to cost for 300 centimeters of
      streamers.

      Now, we can find an equivalent ratio to find the cost for 300
      centimeters of streamers.

4/4 The streamers cost $0.27 per 300 centimeters.

nadezda [96]

Answer:

Tn = 4(-6)^n-1

Step-by-step explanation:

Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....

The sequence is a geometric sequence

Tn = ar^n-1

a is the first term

a = 4

r = -24/4 =144/-24

r = -6

Substitute

Tn = 4(-6)^n-1

In order to solve for this equation, we are going to multiply 7.70 by 0.3 to find how much money was taken which was 2.31.

Subtract2.31 from 7.70 to recieve your new price :)

7.70*0.3=2.31\\7.70-2.31=5.39

Use substitution to solve each system of equations.<br> y = 5x -2<br> 3 x- 5y =4
Nezavi [6.7K]
  • x = 3/11
  • y = -7/11

Step-by-step explanation:

y = 5x - 2…Equation 1

3x - 5y = 4…Equation 2

Subtitute value of y to Equation 2 :

3x - 5(5x - 2) = 4

3x - 25x + 10 = 4

-22x + 10 = 4

10 - 4 = 22x

6 = 22x

6/22 = x

<u>3/11 = </u><u>x</u>

Subtitute value of x to one of Equation :

for example Equation 2…

3x - 5y = 4

3(3/11) - 5y = 4

9/11 - 5y = 4

9/11 - 4 = 5y

(9 - 44)/11 = 5y

(-35)/11 = 5y

(-35)/11 × 1/5 = y

<u>-7/11 = y</u>
