Answer:
The answer is A, (1,2).
Step-by-step explanation:
Hope this helps!
8x-4(x+1) = 0
x =1
y = 1 + 1
y = 2
(x,y) = (1,2)
2 = 1 + 1
8 x 1 - 4 x 2 = 0
Simplify
2 = 2
0 = 0
Solution = (1 , 2)
Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for 
. Now we can divide both sides by 3, getting
. we subtract the first equation from our equation we just got, getting 
y= (5,-5). once we plug that in, we get 
, 
x = (-3,3)
Answer:
66 girls
Step-by-step explanation:
Givens:
●120% boys of girls
▪︎1.2 × g
☆when g is the number of girls
●80 boys
▪︎meaning you can set up a proportion
Solving:
g × 1.2 = 80
g=80/1.2
g=66.66
So, since you can't go over percent, the answer is 66.
Checking:
g × 1.2 = 80
66 × 1.2 = 80
80=80✅
