Answer:
4/9
Step-by-step explanation:
4 plus 3 plus 2 = 9 total amount of scraps, goes on the denominator.
there are 4 orange scraps which is your numerator.
so it is 4/9 or a 44% chance/probability in getting an orange scrap.
Simplifying
3[x + -1] = 12
Reorder the terms:
3[-1 + x] = 12
[-1 * 3 + x * 3] = 12
[-3 + 3x] = 12
Solving
-3 + 3x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 3x = 12 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = 12 + 3
3x = 12 + 3
Combine like terms: 12 + 3 = 15
3x = 15
Divide each side by '3'.
x = 5
Simplifying
x = 5
It's 1 mile. She ran an 8th if an mile. If the ran 1/8 of a mile 8 times, it adds up to 1 mile.

Answer:
x=10
Step-by-step explanation:
1/2x+4=9
subtract 4 from both sides
1/2x=5
multiply both sides by 2 to get x by itself
x=10
