8/9
You have to put them all in the same type of decimal :
-1/2= -0,5 and 8/9 = 0,8888888888
Therefore you just have to see which one of the three numbers is bigger
1) Ratio - 4:1
thus, 4x + 1x = 20
5x = 20
thus, x = 20/5 = 4
thus, x = 4
and, 4x = 16
Thus, the answer is (C) 16 boys and 4 girls
2) According to distributivity, a(b+c) = ab + ac
Thus, the answer is (C)
Inverse functions will be given by the following equation:

k is a constant value that the two variables must multiply to.
Plug in your t and r values:

k = 385.
Now we'll have to find a value that multiplies with 65 to equal 365.
Set up the following equation:

This equation can also be treated as the following:

Divide both sides by 385 to get x by itself:

The answer is
C. about 5.92 hrs to drive the same distance of 385 miles.
supplement of 68.9° = 180° - <span>68.9° = 111.1° = 111° 06'

Think of 6y as
y + y + y + y + y + y
Now subtract a y from that.
y + y + y + y + y + y - y = y + y + y + y + y = 5y
