Answer:
x=0
y=4
Step-by-step explanation:
x=8-2y
3y=-x+12
first make it
ax ( + or - ) by = c
x+2y=8
x+3y=12
now subtract the equations
x+2y=8
- (x+3y=12)
-----------------
-1y=-4
y=4
x+2(4)=8
x+8=8
x=0
Answer:
x < 1/6
Step-by-step explanation:
In the equation 10 – 2(3x – 1) > 6x + 10, start by using the distributive property. Once you've done that, you'd now get 10-6x+2 > 6x+10.
Now, add 10 and 2 togther to get -6x+12 > 6x+10.
Subtract 6x to both sides and subtract 12 to both sides and now you'll get
-12x > -2.
Now, divide each side by -12 to get x < 2/12 or 1/6. Notice how the sign is flipped since you divided by a -.
A. 6x + 4x - 6 = 24 + 9x
10x -6 = 24 + 9x
+6 +6
10x = 30 + 9x
-9x -9x
1x = 30 this has an infinite number of solutions.
there are 8 numbers and you want to get either a 3 or an 8
3 or 8 is 2 numbers out of the 8
so you have a 2/8 reduced to a 1/4 probability of getting them.
