Answer:
C
10 x (p+2) = 30
10 x 2 = 20 30 - 20 = 10 10 ÷ 10 = 1
P = 1
10 x (1 + 2) = 30
The answer is 3.5 + 1.5x = 12.5. So the answer would be C.
The component of mathematics fluency is most likely the goal of this type of assessment is Rate.
GIven,
A local school district requires all fourth graders to complete a 20-minute test containing 200 multiple-choice mathematics problems.
The component of mathematics fluency is most likely the goal of this type of assessment is Rate.
The school district is assessing the rate because they are seeing how many questions students can answer in a given time frame.
Hence, The component of mathematics fluency is most likely the goal of this type of assessment is Rate.

There are 360 degrees in a circle. 1/4 * 360 = 90 degrees
90 degrees > 60 degrees meaning Miguel cut the larger piece by 30 degrees
Add 1 to both sides:
In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that
Under this assumption, we square both sides and we have
The solutions to this equation are
But since we can only accept solutions greater than -1, we discard 
and accept 
.
In fact, we have
and
which is the only solution.
