Answer: a.) The printing press bc .25×200+35=85 and .15×200+50=80. And 80<85.

b.) 150 programs are needed to make them the same.

.25x+35=.15x+50 is 150.

Subtract .15x from both sides

Subtract 35 from both sides

Divide both sides by.10

Shelly biked 21 miles in 4 hours. What is Shelly's average speed in miles per hour? At that same rate how many hours will it tak
Vedmedyk [2.9K]

So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.

<span>75 lbs of Earl Grey 225 lbs of Orange Pekoe Some definitions. E = number of pounds of Earl Grey (300-E) = number of pounds of Orange Pekoe Expression for selling price of new blend P=300*4.5 "there is to be no difference in revenue from selling the new blend versus selling the other types." so P = 6E + 4(300-E) Set them equal to each other, then solve for E 300*4.5 = 6E + 4(300-E) 1350 = 6E + 1200 - 4E 150 = 6E - 4E 150 = 2E 75 = E So 75 lbs of Earl Grey was used and 300-75 = 225 lbs of Orange Pekoe</span>
