4 7/8 + (-6 1/4) how do I find common denominators?

1 answer:

4 0

Find a number that both of the denominates make the same number for example if one denominator is 1/7 and the other is 2/6 then you

2/6 * 7 = 14 over 42 then the other one would be 1/7 *6 which would be 6 over 42 you find common denominators by finding a number both of the bottom ones can equal. hope this helps

Answer:

the number of vegetables did farmer bring in the market is 1764 vegetables

Step-by-step explanation:

The computation of the number of vegetables did farmer bring in the market is shown below:

= 18 bags × 42 kgs + 28 bags × 36 kgs

= 756 + 1008

= 1764 vegetables

Hence, the number of vegetables did farmer bring in the market is 1764 vegetables

Answer:

x = 2, and 6

x = 2 , 6

Step-by-step explanation:

The quadratic function to analyze is: $y = -x^2+8x-12$

In order to find where the corresponding parabola intercepts the x axis, we set it equal to zero (y = 0):

$y = -x^2+8x-12\\0 = -x^2+8x-12\\x^2-8x+12=0$

This equation is easy to solve by factoring. We look for a air of integer numbers whose product equals the constant term "12", and whose combinig renders the coefficient of the middle term of the trinomial "-8".

The two such numbers are "-2" and "-6". We use them to split the middle term, and then solve by factoring by grouping:

$x^2-8x+12=0\\x^2-2x-6x+12=0\\(x^2-2x)+(-6x+12)=0\\x(x-2)-6(x-2)=0\\(x-2)(x-6)=0$

For the product of two factors to render zero, we need either one to be a zero.This means that (x-2)=0 (that is x = 2), or (x-6)=0 (that is x = 6).

So, there are two x-intercepts: x= 2, and 6
