Answer:

D. –5.2 + (–6.4) = –11.6

Step-by-step explanation:

First, you can eliminate A and C because 5.2 is positive. Since the red arrow is pointing left, it indicates that the number (-5.2) is negative.

Then, you look at the second arrow, the green one. It is pointing left, so it would be -6.4.

I hope this helps :)

Answer:

1 : 12 : 4

Step-by-step explanation:

Let A, G, C represent the ages of Alex, George, and Carl, respectively. We are told that ...

A = G +12

C = 3A . . . . . . . we read this as "3 times as old"; not "3 times older"

A + G + C = 68

Substituting for G and C, we have ...

A + (A -12) +(3A) = 68

5A = 80 . . . . . add 12

A = 16 . . . . . . . divide by 5

The other ages are then ...

G = A-12 = 16 -12 = 4

C = 3A = 3·16 = 48

The ratios are ...

G : C : A = 4 : 48 : 16

G : C : A = 1 : 12 : 4

Ok...we got 250 people
30% are French, 35% are Americans, 20% are Germans....thats 85%.
This means 15% are from other countries

3 not from other countries...
0.85 * 0.85 * 0.85 = 0.6
