Answer:
4/12 = 1/3
8/12 = 2/3
Step-by-step explanation:
answer 1: 12 divided by 3 equals 4
answer 2: that number (4) multiplied by 2 equals 8
therefore four twelfths equal one third and eight twelfths equal two thirds
Your very stupid but the answer is 4

Simplifying
2x + 4 + -1(1000 + 4x) + 50 = 9x + 40 + 2 + -3 + 2x
2x + 4 + (1000 * -1 + 4x * -1) + 50 = 9x + 40 + 2 + -3 + 2x
2x + 4 + (-1000 + -4x) + 50 = 9x + 40 + 2 + -3 + 2x
Reorder the terms:
4 + -1000 + 50 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: 4 + -1000 = -996
-996 + 50 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: -996 + 50 = -946
-946 + 2x + -4x = 9x + 40 + 2 + -3 + 2x
Combine like terms: 2x + -4x = -2x
-946 + -2x = 9x + 40 + 2 + -3 + 2x
Reorder the terms:
-946 + -2x = 40 + 2 + -3 + 9x + 2x
Combine like terms: 40 + 2 = 42
-946 + -2x = 42 + -3 + 9x + 2x
Combine like terms: 42 + -3 = 39
-946 + -2x = 39 + 9x + 2x
Combine like terms: 9x + 2x = 11x
-946 + -2x = 39 + 11x
Solving
-946 + -2x = 39 + 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
-946 + -2x + -11x = 39 + 11x + -11x
Combine like terms: -2x + -11x = -13x
-946 + -13x = 39 + 11x + -11x
Combine like terms: 11x + -11x = 0
-946 + -13x = 39 + 0
-946 + -13x = 39
Add '946' to each side of the equation.
-946 + 946 + -13x = 39 + 946
Combine like terms: -946 + 946 = 0
0 + -13x = 39 + 946
-13x = 39 + 946
Combine like terms: 39 + 946 = 985
-13x = 985
Divide each side by '-13'.
x = -75.76923077
Simplifying
x = -75.76923077
Please dont get mad if I am incorrect! :)
I hope this helps! Have a great day!</span>
Answer:
8 ten dollar bills
20 fifty dollar bills
Step-by-step explanation:
x = number of 10 dollar bills
y = number of 50 dollar bills
x+y = 28
10x+50y = 1080
Multiply the first equation by -10
-10x -10y = -280
Add this to the second equation
-10x -10y = -280
10x+50y = 1080
-----------------------
40y = 800
Divide by 40
40y/40 = 800/40
y = 20
Now find x
x+y =28
x+20 = 28
x = 28-20
x= 8
