Answer:
13.13
Step-by-step explanation:
39.39 ÷ 3
13.13
There is not a lot of work
Looking at it we can tell that 3 will go into 3 one time, and 3 will go into 9 three times because:
1 x 3 = 3
3 x 3 = 9
Mid point of x:
{2-(-6)} : 2
8 : 2
4
mid point of y:
(5-3) : 2
2 : 2
1
so (4,1)
Answer:
x=5+b/2
Step-by-step explanation:
move all terms that dont contain x to the right, and solve
Answer:
infinitely many
Step-by-step explanation:
Add 12-y to both sides of the second equation to put it into standard form like the first equation:
y +(12 -y) = (x -12) +(12 -y)
12 = x - y . . . simplify
x - y = 12 . . . . second equation in standard form
We see this is identical to the first equation. That means every solution of the first equation is also a solution of the second equation. There are infinitely many solutions.
Answer:
Grace is right
Step-by-step explanation:
3(2-x)-2(6x-8)=
so:
3×2 is 6
3×(-x) is -3x
-2×6x is -12x
-2×(-8) is 16 because -×- equals +
3(2-x)-2(6x-8)
=6-3x-12x+16
= -15x+22
