Reasons:
(1) Given
(2) their 2 non-common sides in 1 ray
(3) definition of: supplemental angles
(4) Substitution
(5) Opposite angles are congruent (equal)
(6) Substitution
(7) Definition of supplementary angles
So you have the equations
x + 4y = 6
x + 3y = 5
Subtract the two equations.
You get y = 1.
The only answer with a value of y = 1 is A
A is your answer.
Have a nice day! :)
Answer: Create intervals, then count the number of countries that fall in each interval.
When you create a frequency table, you have set intervals. In this case, our small number is close to 0 and our largest number is 4.5. We could create an interval for each number. Then, count the number of countries in each.
It would look like:
Interval Frequency
0-0.99 1
1-1.99 5
2-2.99 5
3-3.99 2
4-4.99 1
31 is 25x3+8x3=51 because you multiply each of the numbers for it to equal 51
Answer:
x=16/13
y= -9/13
Step-by-step explanation:
A: -4y=-x+4
B: y+3x=3
4B: 4y+12x=12
A+4B: 12x= -x+16
-----> 13x=16
x=16/13
-4y= -16/13+4
4y=16/13-4
y=4/13-1= -9/13
