He has 12 dollars and five quarters.
Let X represent the number of dollar bills he has and Y represent the number of quarters he has. From the information given, we know the following:
X=Y+7
AND
X+.25Y=13.25
Solve for X and Y.
Using the value of X from the first equation in the second equation, we get:
(Y+7)+.25Y=13.25
1.25Y+7=13.25
1.25Y=13.25-7=6.25
Y=6.25/1.25=5
Plugging 5 in for Y in the first equation gives us X=5+7=12.
seven
5 dimes 2 quarters
Seven and three quarters can be expressed as 7.75. Since there are 4 quarters in a dollar, you can convert this to quarters by multiplying 7.75 by 4. This gives you 31 quarters, since 7 times 4 is 28 and 3 times 4 is 3, adding up to 31.
2 quarters and 5 dimes
1700/100 = 17 Therefore, $1700 is equal to seventeen $100 bills.
seven
5 dimes 2 quarters
One dollar
OK, so you do 7x4 (seven is the main number, and 4 quarters are a whole). The answer to 7x4 is 28. Then in a half there are 2 quarters, so you add 2 to 28 which is 30
3 quarters 1 dime 3 nickles
Seven and three quarters can be expressed as 7.75. Since there are 4 quarters in a dollar, you can convert this to quarters by multiplying 7.75 by 4. This gives you 31 quarters, since 7 times 4 is 28 and 3 times 4 is 3, adding up to 31.
Only three in the U.S.A
2 quarters and 5 dimes
1700/100 = 17 Therefore, $1700 is equal to seventeen $100 bills.
Well, honey, if you can't do basic math, I'm not sure how you made it this far in life. Seven twenty dollar bills will make 140 dollars. So, count out those bills and stop bothering me with your simple arithmetic questions.
Two quarters of seven hundred is 350.
One and seven hundreds. If its for money, it would be: One dollar and seven cents. One point zero seven.
