no because you wouldn't switch the fraction upside down to make it opposite.

Answer:

What Doug probably means to say is that the reciprocal of -2/5 is 5/-2. So, by this definition, Doug would be correct. However, you would not usually call it the "opposite" of a number, rather, the reciprocal.

The numbers are reciprocals of the other as their product is equal to one "-2/5 * 5/-2 = 1"

-3.1x+7-7.4x-1.5x-6(x-3/2
nalin [4]

Answer:

-2(9x-8)

Step-by-step explanation:

We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)

Open the parenthesis

-3.1x+7-7.4x-1.5x-6(x-3/2)

= -3.1x+7-7.4x-1.5x-6x+6(3/2)

= -3.1x+7-7.4x-1.5x-6x+9

Collect like terms

= -3.1x-7.4x-1.5x-6x+7+9

= -12x-6x+16

= -18x+16

= -2(9x-8)

Hence the simplified form of the expression is -2(9x-8)

Answer:

Assuming that \overline{AOC} is a diameter.

Given that m\angle{BAC} \: = \: 66°

And that point O is the center of the circle

\boxed{m\angle{BAC} \: = \: 57°}

Explanation:

Because angle AOB is subtended by arc AB from point O.

Arc AB is equal to the measure of that angle.

Since arc ABC is subtended by the diameter, the arc is 180°.

Me and my daughter are having a disagreement on this question, I would appreciate the help.
elena-14-01-66 [18.8K]

Answer:

(4t - 8/5) - (3 - 4/3t) = 16/3t - 23/5

5(2t + 1) + (-7t + 28)= 3t+33

(-9/2t +3) + (7/4t + 33) = -11/4c+56

3 (3t-4) - (2t + 10)= 7t -22

Sooo Sorry that it took soooo long! Hope this helps!!!

Happy holidays!!
