Mega Writer pack: 6color:9black ratio or 9 black pens out of 15 total pens.
Mini Writer pack 3color:6black ratio or 6 black pens out of 9.
6:9 is not equal to 3:6 and 9/15 is not equal to 6/9.
Answer:
86
Step-by-step explanation:
Let the number be 10x + y. So, the reversed number is 10y + x.
The sum is 154.
So, (10x + y) + (10y + x) = 154
⇒ 11x + 11y = 154
⇒ x + y = 14 ..... (1)
Again, given that ones digit in the original number is 2 less than the tens digit.
So, y = x - 2 ...... (2)
Now, solving (1) and (2) we get,
x + x -2 = 14
⇒ 2x = 16
⇒ x = 8
So, from equation (2), y = x - 2 = 8 - 2 = 6
Therefore, the original number is 10x + y = 10 × 8 + 6 = 86 (Answer)
Set up an equation when n is the number and solve:
10 </= 4(2n + 3)
10 </= 8n + 12
-12 - 12
-2 = 8n
/8 /8
<u><em>n = >/= -1/4
</em></u>The number is less than or equal to <em><u>-1/4</u></em>.

He has $4.40, the quarters, nickels, and dimes added up to $1.80, subtract that from $6.20 and you get $4.40
If the total value of the coins is $15. The number of each type of coin is: 31 quarters, 72 dimes.
<h3>Number of each type of coin</h3>
Let D = number of dimes
Let Q = the number of quarters
Equations
d + q = 103
0.10d + 0.25q = 15
d = 103 -q
0.10(103 -q) + 0.25q = 15
10.3 - 0.10q + 0.25q = 15
0.15q = 4.7
q=4.7/0.15
q=31 quarters
Substitute q into second equation
D+31=103
D=72 dimes
Therefore the number of each type of coin is: 31 quarters, 72 dimes.
