3x-4y=-5
-x+2y=3
Multiply the second by one:
3x-4y=-5
-2x+4y=6
Combine the equations:
x = 1
Substitute x and solve for y:
-2*1+4y=6
-2+4y=6
4y=8
y=2

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56
uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.

(a-12)x=a+8 if this equation has no solution and a is a constant. what is the value of a
lbvjy [14]

Answer:

a=12

Step-by-step explanation:

If you solve for x, you divide by (a-12) to isolate x on the left side:

x = (a+8)/(a-12)

If the numerator is 0 you will be dividing by zero, which invalidates the solution. This will happen for a=12.
