Answer:
2/5
Step-by-step explanation:
5+4+1 = 10. If you have 4 nickels out of 10 coins, it means there is a 4/10 chance of selecting one, but to simplify, 2 is the greatest common factor, so you would divide each number.
4/2 = 2.
10/2 = 5.
The answer is 2/5.

Problem # 1
3w-10=4w+5
(3w-10) + (10-4w) = (4w+5) + (10-4w)
(3w-10) + (-4w+10) = (4w+5) + (-4w +10)
3w-10-4w+10 = 4w +5 -4w +10
3w-4w=15
-w=15
w= -15 (w is negative 15)
problem #2.
6-2t > 18
6-2t-6 > 18-6
-2t > 12
(-1) (-2t) > 12 (-1)
2t > -12
next divide by 2
2t/2 > -12/2
t > -6 (t is greater then negative 6)
Answers:
A) 
C) 
Step-by-step explanation:
<u>Part 1:</u>
We have the followig equation:
Calculating the least common multiple (l.c.m) in the denominator in the left side of the equation, being l.c.m=15:
Solving for the left part of the equation:
Operating with cross product:
Applying the distributive property:
Isolating 
:
Dividing numerator and denominator by 11:
Hence, the correct option is A
<u>Part 2:</u>
We have the followig equation:
Operating with cross product:
Isolating 
:
Hence, the correct option is C
