A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solu

nlexa [21]

Step-by-step explanation:

If x = the amount of 12% and y = the amount of 20%, then x + y = 80

Since we need 80 grams of 15%, 80(.15) = 12.

We are given that .12x + .20y = 12.

We can solve the first equation for x or y. Let's do x.

x = 80 - y

.12(80 - y) + .20y = 12

9.6 - .12y + .20y = 12

.08y = 2.4

y = 30

x = 80 - 30 = 50

Angel jogged around the park in 1 1/4 hr chris jogged same distance in 5/6 hrs how much longer did angel take then chris in hr??

QveST [7]

You will have to get the difference and get a common denominator but first combine the mixed number:
$1 \: \frac{1}{4} - \frac{5}{6} = \frac{5}{4} - \frac{5}{6} = \frac{15}{12} - \frac{10}{12}$
Then subtract the numbers
$\frac{15}{12} - \frac{10}{12} = \frac{5}{12}$
Angel took 5/12 hours longer than Chris
