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.

Answer:
9 3/4
Step-by-step explanation:
Pounds of bananas=2 7/8
=23/8
Pounds of apple=3 1/2
=7/2
2 bags of oranges=2 3/4 each
11/4 each.
Total pounds of oranges=2(11/4)
=22/4
Total pounds of fruits Marisol bought from the market=pounds of bananas+pounds of apples+pounds of oranges
=28/8+7/2+22/8
Find the L.C.M and add them
The L.C.M=8
Total pounds of fruits =28+28+22/8
=78/8
=9 6/8
Equivalent to
9 3/4
Answer:
To avoid expansion, you can just use the power of a power rule and multiply the two exponents from the start.
Step-by-step explanation:
(<em>x</em>^4)^3
= <em>x</em>^4×3
= <em>x</em>^12
I hope this helps you
-( 3.5+1/3) ÷ 2.4+3/4
- 16/3 ÷ 11/4
-16/3 × 4/11
- 64 / 33
- 1 31 /33
