Answer:
y = 2
Step-by-step explanation:
-3y + 6 = 0
-3y = -6
y = -6/-3
y = 6/3
y = 2
Answer:
0.486% of world population lives in Canada.
Step-by-step explanation:
Given: World Population= 7691 million.
Canada Population= 37.4 million.
Now, finding the percentage of world population lives in Canada.
⇒ 
⇒ 
∴ 
Hence, 0.486% of world population lives in Canada.
Answer : 
(1) 
Use FOIL method to mulitply (3x – 5)(3x – 5)
(2) 
Use FOIL method to mulitply (3x - 5)(3x + 5)
(3) 
Use FOIL method to mulitply -(3x + 5)(3x + 5)
(4) 
Use FOIL method to mulitply -(3x + 5)(3x - 5)
So equation 2 is true

They would need to sell 48 tickets at the door to reach their goal.
Answer:
2
Step-by-step explanation:
Let's solve the given system of equations.
<u>Given system</u>
x +3y= 10 ----(1)
-2x -2y= 4 ----(2)
From (2):
-2(x +y)= 4
Dividing both sides by -2:
x +y= -2 ----(2)
Thus, options 3 and 4 are incorrect as x +y≠ -2.
(1) -(2):
(x +3y) -(x +y)= 10 -(-2)
Expand:
x +3y -x -y= 10 +2
2y= 12
Divide both sides by 2:
y= 12 ÷2
y= 6
Substitute y= 6 into (2):
x +6= -2
x= -6 -2
x= -8
Options (1) and (2) differs only by the value of the expression of -x +y. Thus, let's find its value in the given system of equations.
-x +y
= -(-8) +6
= 8 +6
= 14
Thus, option 2 is the correct option.
