Answer:

13.  b.  4 + 5x = 29; $5.

14.  c.  74 + w = 3w + 6; 34 pounds.

15.  b.  $42.5.

Step-by-step explanation:

13. 4 + 5x = 29

5x = 29-4 = 25

x = 5.

14. 74 + w = 3w + 6

68 = 2w

w = 34.

15. Let x be the money he got last year. Then:

2x + 5 = 90

2x = 85

x = $42.5.

Alenkasestr [34]

Answer:

C. 1/4 lb of chicken per person

Step-by-step explanation:

Find the rate of change for the situation.

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.

A. 9/17lb per person

B. 4 lb per person

C. 1/4 lb per person

D. 36 people

Solution

9 lbs of chicken for 36 people

Chicken per person = Total lbs of chicken / Total number of people

= 9 lbs / 36 people

Chicken per person = 1/4 lb of chicken per person

17 lbs of chicken for 68 people

Chicken per person = Total lbs of chicken / Total number of people

= 17 lbs / 68 people

= 1/4 lb of chicken

Chicken per person = 1/4 lb of chicken per person

Therefore, the rate of change of the situation = 1/4 lb of chicken per person

A pharmacist has 80 milileters of a 25 percent saline solution. Which expression can be used to find the percentage of the conce
Thepotemich [5.8K]

Answer:


Step-by-step explanation:

Final concentration % = [grams of salt / mililiters of solution] * 100


grams of salt = grams of salt from solution 1 + grams of salt from solution 2


grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g


grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x


mililiters of final solution = mililiters from solution 1 + mililiters from solution 2


mililiters of final solution = 80 mililiters + x mililiters


=> Final concentration, %  =  [0,10x + 20 g] / [x + 80 mililiters] * 100

Determine whether quantities vary directly or inversely and find the constant of variation.
insens350 [35]
This is a problem in direct variation.  For every five minutes that goes by, Liz utters 225 words.  The general form of an equation of direct variation is 

w = k x, where w is the # of words, k is the constant of proportionality and x is the number of minutes that have elapsed.

Find k by dividing 225 words by 5 minutes, to find the number of words per minute.

Next:  How many minutes are there between 10:30 a.m. and 11:15 a.m.?  Calculate w=kx, using your constant of proportionality, k, and that number of minutes.
