Mario invested $475 in $45 and $25 stock shares. The number of $25 shares was 5 less than 3 times the number of $45 shares. How

Anit [1.1K]

$\text{Answer : Number of \$45 shares} =120$

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$

Explanation:

Let Number of $45 shares be x

Let number of $ 25 shares be 3x-25

According to question,

$x+3x-5=475\\\\4x-5=475\\\\4x=475+5\\\\4x=480\\\\x=\frac{480}{4}\\\\x=120$

So,

$\text{Number of \$45 shares} =120$

$\text{Number of \$25 shares }\\\\= 3\times 120-5\\\\=360-5\\\\=\$355$

3/7 of which is 2 1/14

mash [69]

Answer:

4 and 5/6; 29/6.

Step-by-step explanation:

3/7 of x is 2-1/14.

(3/7)x = 29/14

x = (29/14) * (7/3)

x = (29/2) * (1/3)

x = 29/6

3/7 of 4 and 5/6 is 2 1/14.

Hope this helps!

(1 point) All that is left in a packet of candy are 7 reds, 3 greens, and 3 blues.

Sauron [17]

Answer:

A 21 /169

B independent

Step-by-step explanation:

The total number of candies is 7+3+3 = 13

P( 1st red) = red/total = 7/13

Since the candy is put back there are still 13 candies in the dish

P(2nd green) = green/total = 3/13

P( red, then green) = P( 1st red) * P(2nd green)

= 7/13* 3/13 = 21/169

The events are independent since the candies are put back
