Audrey has 32 dimes and quarters in her piggy bank with a total value of $6.50. how many of the coins are dimes and how many are

fgiga [73]

D + q = 32....d = 32 - q
0.10d + 0.25q = 6.50

0.10(32 - q) + 0.25q = 6.50
3.20 - 0.10q + 0.25q = 6.50
-0.10q + 0.25q = 6.50 - 3.20
0.15q = 3.30
q = 3.30 / 0.15
q = 22 <=== 22 quarters

d + q = 32
d + 22= 32
d = 32 - 22
d = 10 <=== 10 dimes

a patient was supposed to take 560 mg of medicine but took on The 420 mg what percent of medicine does she take

Sav [38]

You need to set the correct porportion. x is the percent value you want to find. 100 is the maximum percentage. 420mg is what was taken out of the maximum 560mg dose.

$\frac{x}{100} \times \frac{420}{560}$

You will cross multiple.

$560x = 42000$

you will divide 42000 by 560

$\frac{560x}{560} = \frac{42000}{560}$
$x = 75$

The complete answer will be: The patient took 75% of the 560mg dose of medication.
