Answer : 96
x – y = 16 --------> equation 1
1/8 x + 1/2 y = 52
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
1/8 x + 1/2 ( -16 + x ) = 52
1/8x - 8 + 1/2 x = 52
1/8x + 1/2x - 8 = 52
Take common denominator to combine fractions
1/8x + 4/8x -8 = 52
5/8x - 8 = 52
Add 8 on both sides
5/8x = 60
Multiply both sides by 8/5
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.

The length of QJ is 4√20 units if the QJ = 4×PQ after using the intersecting chords theorem.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
By intersecting chords theorem:
QM×QL = QJ×PQ
10×8 = QJ(QJ/4)
4×80 = QJ²
QJ = 4√20 units
Thus, the length of QJ is 4√20 units if the QJ = 4×PQ after using the intersecting chords theorem.
