**Answer:**

6:1:2

**Step-by-step explanation:**

Let a = Able's score, b = Ben's score, and c = Cal's score.

Since

Able's score was 6 times Ben's score, that means a = 6b.

Cal's score was a third of Able's score, so that means c = a/3. And since a = 6b, that means c = 6b / 3 = 2b.

Thus, the ratio of Able's score to Ben's score to Cal's score, a:b:c, is 6:1:2, because c is twice as much as b and a is 6 times as much as b.

The answer is D the last one

Answer: about 40%

Step-by-step explanation:

315,000,000/7,700,000

**Answer:**

x = -7, y = 5

**Step-by-step explanation:**

a) x + 9y = 38, b) 3x + 7y = 14

From a)

x = 38 - 9y ---- (Equation 1)

From b)

{3*(38 - 9y)} + 7y = 14 ----- (From equation 1)

114 - 27y + 7y -14 = 0

100 - 20y = 0

20y = 100

y = 5

From a)

x + (9*5) = 38 (substituting the value of y = 5)

x + 45 = 38

x = 38 - 45

x = -7
