Answer:
x=3, y=-1
Step-by-step explanation:
We are already given an equation solved for x, making substitution much easier. We know x=4y+7, meaning we can put 4y+7 whenever we see x in the second equation
2x-6y=12
We substitute 4y+7 in place of x
2(4y+7)-6y=12
Now we only have one variable to work on, distribute the 2
8y+14-6y=12
Combine similar terms, 8y-6y=2y
2y+14=12
Subtract 14 from both sides
2y=-2
y=-1
Now we plug in -1 for y in the first equation to find x
x=4(-1)+7
x=-4+7
x=3
Answer:
The answer is C
Step-by-step explanation:
Wheres the equation lmaooooo
260
650 times 0.4 (20%+40%)
Since the kids and women are 60%
100%-60%= 40% so 40% were men
I’m not sure but I think it’s right hope it helps tho
0.0062 is 0.062%
If this helped smash that thanks button
