Answer:
equal or balanced
Step-by-step explanation
the = demonstrates the amounts need to be the same
-5x+3y=-6
9x-4y=1
try adding them together and get
9x-5x+3x-4y=1-6
4x-y=-5
multiply the equation by 3
12x-3y=-15
add this euation to -5x+3y=-6 and get
12x-5x+3y-3y=-6-15
7x=-21
divide both sides by 7
x=-3
subsitute x=-3 for x in any equation
9x-4y=1
9(3)-4y=1
27-4y=1
-4y=-26
divide both sides by -4
y=6 and 2/4 or 6.5
x=-3
y=6.5

Answer:
100 fiddler crabs
Step-by-step explanation:
If the 30 crabs are a representation of the entire population, then 6 marked crabs in a population of 30 would mean that
6 / 30 = 0.20 or 20%
20% of the entire crab population are marked. Since we know that a total of 20 fiddler crabs are marked in the pond then we can divide this number of marked crabs by 20% in decimal form to get the estimated total size of the fiddler crab population
20 / 0.20 = 100 fiddler crabs
Answer:
The correct option is C
C) Hungary
Step-by-step explanation:
Suppose we draw a vertical number line such that it shows elevations of different countries. For y=0, we get India. As all the rest of the values, expect Hungary, are given negative values, hence all the value will lie below India in the numbers line. The only country that lies above India in the number line is Hungary as only it has a positive number for the elevation. So the lowest elevation above 0 will be shown of Hungary which is 78.
