Answer:

(D)\left(-\dfrac38\right)\left(-\dfrac57\right)\left(-\dfrac14\right)

Step-by-step explanation:

The given options are:

(A)\left(-\dfrac38\right)\left(-\dfrac57\right)\left(\dfrac14\right)\\(B)\left(\dfrac38\right)\left(-\dfrac57\right)\left(-\dfrac14\right)\\(C)\left(\dfrac38\right)\left(\dfrac57\right)\left(\dfrac14\right)\\(D)\left(-\dfrac38\right)\left(-\dfrac57\right)\left(-\dfrac14\right)

The key to determining which product is negative is to understand the rule of sign multiplication.

Now:

  • The product of even negative terms is positive
  • The product of odd negative terms is negative.
  • The product of positive will always be positive.

In Options A and B, the number of negative signs is even, therefore our result is positive.

In option C, all the terms are positive, therefore our result will be positive.

In Option D, the number of negative signs is odd, therefore our result is negative.

Exterior angle c = the sun of the two opposite interior angles a and b.

10x -23 = 5x -17 + 7x -26

Combine the right side:

10x -23 = 12x -43

Add 43 to both sides:

10x +20 = 12x

Subtract 10x from both sides:

20 = 2x

Divide both sides by 2

X = 10

Now you have x replace it in the equation for A:

A = 5x -27 = 5(10) -27 = 50-27 = 23

Angle A = 23 degrees.

Work out b(4½-3⅔)+1⅔​
Zolol [24]

Answer:

2 \frac{1}{2}

Step-by-step explanation:

Change the mixed numbers to improper fractions

(\frac{9}{2} - \frac{11}{3} ) + \frac{5}{3} ← the LCM of 2 and 3 is 6

= \frac{9(3)}{2(3)} - \frac{11(2)}{3(2)} + \frac{5(2)}{3(2)}

= \frac{27}{6} - \frac{22}{6} + \frac{10}{6}

= \frac{5}{6} + \frac{10}{6}

= \frac{15}{6}

= \frac{5}{2}

= 2 \frac{1}{2}
