Answer:

F) 63

Step-by-step explanation:

Find the original total stories 10 + 8 + 16 + 8 = 42.

Original ratio of Mary's stories to total stories is 8/42 or 4/21.

Then form equation 4/21 = 12/x ; multiply both sides of 4/21 by 3.

4/21 = 12/63

The students need to write 63 stories to keep the ratio of Mary's stories to total stories the same.

Two times the quantity of eight times a number plus two is equal to three the quantity of two times the same number minus seven
Effectus [21]

The unknown number is - 2.5

Let the number = n

The equation will be formed as follows;

  • eight times a number plus two = 8n + 2
  • Two times the quantity of eight times a number plus two = 2(8n + 2)
  • two times the same number minus seven = 2n - 7
  • three the quantity of two times the same number minus seven = 3(2n-7)

Our final equation becomes;

2(8n + 2) = 3(2n-7)

Simplify as follow, to determine the unknown number;

16n + 4 = 6n - 21

16n - 6n = -25

10n = -25

n = -2.5

Thus, the unknown number is - 2.5
