Answer:
- 340 quarters
- 1020 dimes
- 1031 nickels
- 2062 pennies
Step-by-step explanation:
x is the number of quarters
__
a) d = 3x . . . . . . the number of dimes is 3 times the number of quarters
b) n = d + 11 = 3x +11 . . . . there are 11 more nickels than dimes
c) p = 2n = 2(3x +11) = 6x +22 . . . . there are twice as many pennies as nickels
d) The total number of coins is ...
x + d + n + p = 4453
x + (3x) +(3x +11) +(6x +22) = 4453
13x +33 = 4453
13x = 4420
x = 4420/13 = 340 . . . . number of quarters collected
3x = 1020 . . . . . . . . . . . .number of dimes collected
1020 +11 = 1031 . . . . . . . number of nickels collected
2·1031 = 2062 . . . . . . . . number of pennies collected
There were 340 quarters, 1020 dimes, 1031 nickels, and 2062 pennies collected.
_____
<em>Check</em>
340 +1020 +1031 +2062 = 4453 . . . as required
He drives 55 miles per hour for x hours. You want to multiply the number of hours by his speed , so you have 55x.
Then you want to subtract that from the total miles he has to drive.
The equation is Y = 385 - 55x
Answer:
425%
Step-by-step explanation:
4 can be written as 4.00 in decimal form. 1/4 can be written as 0.25 in decimal form. When changing a decimal into a percent, you move the decimal to the right two times. If we move the decimal point in 4.00 twice we get 400. If we move the decimal point in 0.25 twice we get 25. If we add 400 and 25 together, we get 425. Therefore, the answer is 425%. Hope this helped! :)
