Answer:

Step-by-step explanation:
Find the LCD because like last time, you cannot add or subtract fractions with different denominators.
LCD = 10
Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.




The middle one because the both need dotted lines can I get a crown
Answer:
The following measurements are:
(Option #4)
(Option #7)
(Option #5)
(Option #2)
Step-by-step explanation:
To begin, we can find the measure of
by applying the inscribed angle theorem: an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.
Since the intercepted arc (RS) is 46 degrees, we have:

Next, we can find the measure of arc QT using the same theorem. So,

Notice that the chord RT is actually a diameter. From the theorem about the inscribed angle including a diameter, we know that the intercepted arc will have a measure of
. Since the arc ST is part of the arc RST, and we know RS is
, we can set up and solve this equation:

We can use the same idea to find RQ. We know that RQT is
and QT is
, so:

D.greater than or equal to one
