When i divide into ratio, i like to think of them as units:
so 24 will be divided into units, where the first thing gets 3 units and the second 5 units. In total those are 3+5=8 units.
so each unit will have 24/8=4
so the division into the two numbers is like this: the first one gets 3 units (3*4=12) and the second 5 (5*4=20)
so it's 12:20.
ANSWER

EXPLANATION
The given function is

We need to find the inverse of this function,
Let

We interchange x an y to obtain,

We solve for y now to obtain,

We divide through by m to get,

Hence the inverse function is ,

For this inverse to exist, the denominator must not be equal to zero,
Thus

The correct answer is A.
Answer: The answer is C, 2 screws.
Answer:
<u>The correct answer is B. 82</u>
Step-by-step explanation:
The numbers are 56 and 26. Let's prove it:
56/5 = 11 and a remainder of 1
56/6= 9 and a remainder of 2
26/5 = 5 and a remainder of 1
26/6 = 4 and a remainder of 2
56 + 26 = 82
<u>The correct answer is B. 82</u>
Answer:
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
<em></em>
Step-by-step explanation:
Total number of coins = 43
Let number of nickels = n
Let number of dimes = d
Let number of quarters = q

Money in n nickels = 
Money in d dimes = 
Money in q quarters = 
Total money = $7.45

The sum of the numbers of nickels and dimes is 3 less than the number of quarters.
i.e.

Let us put the value in (1):

Putting the value of q in (1) and (2):
n+d = 20 .... (3)

(4) - (3):
d = 14
Now, from (3):
n = 6
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
