First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

a(b + c) = ab + ac


Using this, we can multiply the 7 out to the y and 3. This gives us:

7y + 21 = 5y + 8


Now, let's solve for y:

2y + 21 = 8

2y = -13

y = - \dfrac{13}{2}


We can see that there is one solution for this equation because y is equal to one definite value after solving. Thus, our answer is A, one solution.

Answer:

76 degrees.

Step-by-step explanation:

Let as consider O is the center of the circle . So from the figure it is clear that

\angle AOB=44^{\circ}

\angle COD=118^{\circ}

By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.

We know that, \angle BAD=97^{\circ} and angle BOD is the central angle subtended by arc BD.

\angle BOD=2\times \angle BAD

\angle BOD=2\times 97^{\circ}

\angle BOD=194^{\circ}

Now,

\angle BOD=\angle BOC+\angle COD

194^{\circ}=\angle BOC+118^{\circ}

194^{\circ}-118^{\circ}=\angle BOC

76^{\circ}=\angle BOC

m(arc(BC))=76^{\circ}

Therefore, the measure of arc BC is 76 degrees.

38 is what percent of 76?
djyliett [7]
Okay, to find the answer, you would divide the first number by the second number.

   38/76=0.5

To find the decimal as a fraction, move the decimal two spots to the right.

0.5=50%

I hope this helped!
