Jim has a total of 12 coins. Some of them are nickels, and the others are quarters. If he had 12 more nickels, then the value of the nickels would be the same as the value of the quarters. How many quarters does he have?Let n = the number of nickels and q = the number of quarters.

Which two equations can be used to solve this problem? Select the two that apply.

Answer 1

Answer: $n-\ number\ of\ nickels\nq-\ number\ of\ quarters\n\nn+q=12\ \ \ \ | n=12-q\n0,05(n+12)=0,25q\n\n0,05n+0,6=0,25q\ \ \ | substitute\ n=12-q \n\n0,05(12-q)+0,6=0,25q\n\n0,6-0,05q+0,6=0,25q\n\n1,2-0,05q=0,25q\ \ \ | add\ 0,05q\n\n1,2=0,3q\ \ \ | divide\ by\ 1,2\n\nq=4\n\nHe\ has\ 4\ quarters.$

What is 1/5 of 45? please help my 10 yr. Old.

Answers

Answer:
9

Explanation:
To get the fraction of a number, you will simply multiply the fraction by the given number.

For the given, we want to find $(1)/(5)$ of 45.
This can be computed as follows:
$(1)/(5)$ of 45 = $(1)/(5)$ * 45

= $(1*45)/(5)$

= $(45)/(5)$

= 9

Therefore, $(1)/(5)$ of 45 is 9

Hope this helps :)

The product of the numbers 1/5 and 45 will be 9.

Given that:

Numbers, 1/5 and 45

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The product of the numbers 1/5 and 45 will be calculated as,

⇒ 45 x 1/5

⇒ 45 / 5

⇒ 9

What value for n makes this equation true? 4 • 63 = (4 • 60) + (4 • n)

Answers

4 · 63 =(4 · 60) +(4 · 3)

4* 63 = (4* 60) + (4*n)
252 = 240 + 4n
252 - 240 = 240 - 240 + 4n
12 = 4n
4n : 4 = 12: 4
n = 3
