Mary and Jane have $48 to share in the ratio 3:5. How much did each girl 2 points
zubka84 [21]

Answer:

Mary- $18

Jane- $30

Step-by-step explanation:

Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.

x(3+5) = $48

3x + 5x = $48

8x = $48

8x/8 = $48/8

x = $6

3($6):5($6) = $18:$30

Write an explicit rule for each geometric sequence using subscribe notation. Use the calculator and around your answer to the ne
expeople1 [14]

Answer:

a = 256; r = $ \frac{1}{2}  $

Step-by-step explanation:

The general form of the geometric sequence is:

a, ar, ar², ar³, . . .

where 'a' is the first term of the sequence;

'r' is the common difference.

Fourth term of the sequence = ar³ = 32

Sixth term of the sequence   = ar⁵ = 8

Dividing both the equations, we get:

$ \frac{ar^5}{ar^3} = \frac{8}{32} $

⇒ r² = $ \frac{1}{4} $

⇒ r = $ \frac{1}{2} $

Therefore, we get a = 32 X 8

a = 256

The first term of the sequence is 256 and the common difference is $ \frac{1}{2} $.

Hence, the answer.

nekit [7.7K]

Answer:

x=\frac{-1}{6}

Step-by-step explanation:

9(x+1) -4x = 5-(x-3)

9(x+1) -4x = 5-(x-3) \\

9x+9\cdot1-4x=5-\left(x-3\right)

9x+9-4x=5-\left(x-3\right)

\left(9x-4x\right)+9=5-\left(x-3\right)

5x+9=5-\left(x-3\right)

5x+9=5-x+3

5x+9=-x+\left(5+3\right)

5x+9=-x+8

5x+9=-x+8

5x+9+x=-x+8+x

5x+x+9=-x+8+x

6x+9=-x+8+x

6x+9=-x+x+8

6x+9=8

6x+9=8

6x+9-9=8-9

6x=8-9

6x=-1

\frac{6x}{6}=\frac{-1}{6}

x=\frac{-1}{6}
