Mathematics
1 answer:
ollegr [7]3 years ago
8 0

Answer:

d=10

Step-by-step explanation: step 1: 2/5d-1 = 3/5d-3           add 3 to both sides

                                                                   +3          +3

                                            step 2:  2/5d+2 = 3/5d subtract 2/5d to both sides

                                                         -2/5d       -2/5d

                                            step 3:         2 =  1/5d       multiply 5/1 to both sides

                                                              * 5/1 = *5/1

                                                                10 = d

Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour.
Andrews [41]
3t = 5(3-t)
3t = 15 - 5t
3t + 5t = 15
8t = 15
t = 15/8
t = 1 7/8 

7/8 * 60 mins = 52.50 minutes

t = 1 hour and 52.5 minutes

It took Stu 1 hour and 52.5 minutes to hike the trail one way.

Since we are given the values for both rows only in the second column, we can use this to solve for the rest of the missing values. Simply divide 3 by 2.49 and multiply that resultant by and multiply that by any missing value for cookies to find the missing cost. In order to solve for the cookies when cost is given, divide 2.49 by 3 and multiply that resultant. I will solve for the first, third, and fourth columns.

3/29=1.2
For column 1, 1.2*1=1.20
For column 3, 1.2*20=24.10
For column 4, 1.2*100=12.00
