Prove that if d|m and d|n, then d|(m+n)

Mila [183]

$d\mid m$ means to say there is some $k_1$ such that $m=dk_1$ . Similarly, $d\mid n$ is equivalent to saying there exists $k_2[/te]x such that [tex]n=dk_2$ .

Now, $m+n=dk_1+dk_2=d(k_1+k_2)=dk_3$ , i.e. there is some $k_3$ such that $m+n$ is a multiple of $d$ , i.e. $d\mid(m+n)$ .

A bag contains pennies, nickels, dimes and quarters. There are 50 coins in all. Of the coins, 8% are pennies and 30% are dimes.

Gala2k [10]

Answer:

$6.49

Step-by-step explanation:

Pennies = 8% of 50 =4 ; 4x0.01 = 0.04

Dimes = 30% of 50 = 15 ; 15x0.10 = 1.50

Nickels = 10 + 4(number of pennies) = 14; 14x 0.05 =0.70

Quarters = 50 - 33 (total pennies + dimes + nickels ) = 17 ; 17x0.25=4.25

Therefore total amount in bag = 0.04+1.50+0.70+4.25 = $6.49
