<span> here
7 7/8
= [ (8*7) + 7 ] / 8
= (56 + 7) / 8
=63 / 8
similarly,
3 1/4
=[ (4*3) + 1] / 4
= (12 + 1) / 4
= 13/4
----------------------------
now put the values
7 7/8 - 3 1/4
= 63/8 - 13/4
here, take LCM of 8 & 4 which is 8.
now,
[ (1*63) - (2 * 13) ] / 8
= (63 - 26) / 8
= 37/8
= 4 5/8........................[ here, divide 37 by 8 which gives reminder as 5 and divisible value as 4 ]</span>
Your answer would be D. hope that helped
Answer:
The 5th prime number is 11.
Step-by-step explanation:
The only factors of 11 are <u>11 and 1</u> (11 * 1) which makes it a prime number.

=> 38% of students at a college failed mathematics
=> 27% failed physics, and=> 9% failed both. A student is selected at random.
a)If a student failed physics, what is the probability that he or she failed math?
=> 1/38
b)If a student failed math, what is the probability he or she failed physics?
=> 1/27
c) What is the probability that he or she failed math or physics?
=> 1/9
M=Y2-Y1/X2-X1
m=-3-(-6)/0-(-4)
m=-3+6/0+4
m=3/4
The equation is y=3/4x-3
