Answer:
3(4)+g=28
Step-by-step explanation:
3 is the cost of one pair of shoes and 4 is how many shoes were rented. you multiple the 3 times 4 and get 12 and to get the amount of one game you have to subtract the total amount. the equation I came up with might not be what your teacher wants but thats a start. hope it helped!
For x^3-11x^2+33x+45 , we can make it an equation so <span>x^3-11x^2+33x+45=0. Next, we can find out if -1 or -3 is a factor. If -1 is a factor, than (x+1) is factorable. Using synthetic division, we get
x^2-12x+45
___ ________________________
x+1 | x^3-11x^2+33x+45
- (x^3+x^2)
_________________________
-12x^2+33x+45
- (-12x^2-12x)
______________
45x+45
-(45x+45)
___________
0
Since that works, it's either B or D. We just have to figure out when
</span> x^2-12x+45 equals 0, since there are 3 roots and we already found one. Using the quadratic formula, we end up getting (12+-sqrt(144-180))/2=
(12+-sqrt (-36))/2. Since sqrt(-36) is 6i, and 6i/2=3i, it's pretty clear that B is our answer
Answer:
The answer is x = 5
Step-by-step explanation:
The given equation is
25 - 3x = 10
So when we break down this equation, we will have the value of x. Now breaking down the equation and moving variables to the correct positions.
25 - 3x = 10
Moving -3x and 10 to the other sides
25 - 10 = 3x
3x = 25 - 10
3x = 15
Now dividing both sides with 3, we get the following answer
3x/3 = 15/3
x = 5
Breaking down the equation gives us the value of x, i-e 5
