Answer:

2/7 of a cup

Step-by-step explanation:

This means he needs 5/7 of the 2/5 cup of the whole recipe, so it is (5*2)/(7*5) or 10/35 or 2/7 of a cup.

I need to find the least common denominator of x+2/x^2+2x-3 , x-7/x^2+5x+6
grin007 [14]

Answer:

(x + 3)(x - 1)(x + 2)  

Step-by-step explanation:

The fractions are:  

\dfrac{x + 2}{x^{2} + 2x - 3} \text{ and } \dfrac{x - 7}{x^{2} + 5x + 6}

Factor each denominator  

x^{2} + 2x - 3 = (x + 3)(x - 1)\\x^{2} + 5x + 6 = (x + 3)(x + 2)

We must find the least common multiple of the denominators.  We take the maximum power of each separate factor.

      Factors of first fraction = (x + 3) × (x - 1)

Factors of second fraction = (x + 3)             × (x + 2)

                                   LCM = (x + 3)(x - 1)(x + 2)

The lowest common denominator of the two fractions is (x + 3)(x - 1) (x + 2).

The 3 angles form the straight line AB. A straight line equals 180 degrees.

The 3 angles when added together need to equal 180:

2x + 65 + (x + 65) = 180

Simplify by combining like terms:

3x + 130 = 180

Subtract 130 from both sides

3x = 50

Divide both sides by 3

X = 50/3

X = 16 2/3 (16.66667 as a repeating decimal)

Now you have x if you need to solve all the angles replace x with its value and sole:

2x = 2(16 2/3) = 33 1/3

X + 65 = 16 2/3 + 65 = 81 2/3
