Answer:
D(0.10) + Q(0.25) = 10.45
Q = D + 25 (or Q - D = 25)
Step-by-step explanation:
D = number of dimes
Q = number of quarters
D(0.10) + Q(0.25) = 10.45
Q = D - 25 (or D - Q = 25)
We multiply the number of dimes she has by $0.10, because that is the worth of each dime, and we multiply the number of quarters she has by $0.25 because that is the worth of each quarter. We then set that equal to $10.45, the overall value of her coins.
Because she has 25 less dimes than quarters, the number of dimes she has should be 25 less than the number of quarters she has. So the number of quarters she has should be equal to the number of dimes she has plus 25.
Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
In other words, it's asking what fraction is $6.30 out of $35. So let's make a fraction.
![\frac{6.30}{35}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6.30%7D%7B35%7D%20)
Remember that the fraction sign is a division sign. So 6.30/35 = 6.30<span>÷35, which equals 0.18.
Converting the decimal 0.18 to a percent, multiply by 100 (move decimal two places to the right) and tag the % sign at the end.
0.18 = 18%</span>
