Answer:
Number 3 is -17 7/24 yards and Number 2 is -42 1/36 meters
Step-by-step explanation:
Number 3:
-7 2/3 + (-9 5/8)
Then you find common denominator.
-7 16/24 + (-9 15/24)
Add.
-16 31/24
Lastly, Simplify.
-17 7/24
Number 2:
-64 7/9 + 22 27/36
Then you find common denominator.
-64 28/36 + 22 27/36
Add.
-42 1/36
Answer:
50 soldiers must be transferred elsewhere.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
As the number of soldiers decrease, the provisions last for more time. This means that the measures are inversely proportional, and we have an inverse rule of three, using line multiplication, instead of cross.
30 days of provisions - 200 soldiers
40 days of provisions - x soldiers

Simplifying by 40

The provisions will last for 40 days with 150 soldiers, which means that 200 - 150 = 50 soldiers must be transferred elsewhere.
Understand subtraction of rational numbers as adding the additive inverse, p - q = p + (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.
Answer:
x = 1
Step-by-step explanation:
4(2x + 1) - 3 = - 3(x - 4) ← distribute parenthesis on both sides
8x + 4 - 3 = - 3x + 12
8x + 1 = - 3x + 12 ( add 3x to both sides )
11x + 1 = 12 ( subtract 1 from both sides )
11x = 11 ( divide both sides by 11 )
x = 1
