<span>Hey there, Lets solve this step by step.
</span>
<span>"Two times the quantity of a number minus 12”
</span><span>Two times the quantity = 2 * n
</span>
<span>number minus 12 = n - 12
</span>
Therefore
2n-12
Check out the pdf attached to see how to do this problem. It will give you a way of solving all ratio problems. But the final answer 176-124 = 52 there are 52 more girls than boys.
Answer:

q=45?
t=52
Step-by-step explanation:
Answer:

Step-by-step explanation:
a. A fair dice has 6 sides with unique identities.
-The sample space of one throw is 6 and each face has an equal chance of showing up.
-The probability of a 6 is calculated as:

Hence, the probability of a 6 is 
b.A fair die has 6 unique faces.
-Two throws will have a sample space of 12.
-Each face has an equal probability of appearing twice.
-The probability of a 6 on both throws is:

c. A coin has 2 sides(head, tail) and a die has 6 sides.
-The total sample space for the simultaneous throw of a coin and die is 12.
-The resultant sample space is :

Answer:
x = - 3/7
y = - 8/7
Step-by-step explanation:
(2x - 6y = 6)/2 =
x - 3y = 3
x = 3y + 3
Substitution:
6 (3y +3) - 4y = 2
18y + 18 - 4y = 2
14y = -18+2
y = -16/14
y = - 8/7
Substitution:
x = 3(-8/7)+3
x = -24/7 + 3
x = -3/7
