P = 2d
d = 2n.....n = 1/2d
q = d - 3
since dimes is mentioned in relation to quarters, pennies, and the nickels, u would use d as ur variable
ur expression would be : d + (2d) + (1/2d) + (d - 3) = total amount of coins...then u would solve for d, the number of dimes. And once u know that, u can sub that answer back into ur original equations to find the number of pennies, quarters and nickels
Answer:
Solution,
CP of a bicycle=$3000
Marked up=40%
Now,
→40% of $3000
→40/100x$3000
→$1200
→$3000+$1200=$4200
Again,
Discount(d)=30%
→30%of $4200
→30/100x$4200
→$1260
Hence, the discount price of the bicycle is $1260

Answer:
0.216 = 0.6³
Step-by-step explanation:
using the rule of logarithms
• 
x = n ⇔ x = 
0.216 = 3 ⇒ 0.216 = 
Two other ways to write 0.632 is to turn it into a percent. To turn 0.632 into a percent just multiply it by 100. You can do this simply by moving the decimal point to the right twice and adding the percent sign: 63.2%
Another way is by fraction form. To put in in fraction form just look at the decimal and see which is the last place. The last placement it a thousandth. So your denominator is automatically 1000. Then, you look at the decimal and write the decimal and disregard the zero. The fraction you get is 632/1000. Hope this answer helps and mark as brainliest!
