On an uphill hike Ted climbs at 3mph. Going back down, he runs at 5mph. If it takes him forty minutes longer to climb up than run down, then what is the length of the hike? if possible, I would like a clear equation.

Answers

Answer:

He hiked 10 miles.

Step-by-step explanation:

rate x time = distance

The distance up and the distance down are equal

3 mi/1 hr x (h hours + 2/3 hr) = 5 mi/1 hr x h hours

3h + 2 = 5h

2 = 2h

h = 1 hour

3mi/hr x 1 2/3 hr = 5 miles

5 mi/hr x 1 hr = 5 miles

15x—3y=12
Y=5x—4

4x—y=-4
-8x+2y=2

Answers

15x-3y=12
y=5x—4
I'm also not sure what your question is, but this is what I got by solving it like a regular equation.

15x-3(5x-4)=12
15x-15x+12=12
0=12-12
0=0

4x-y=-4
-8x+2y=2

-y=-4-4x /: (-1)
y=4+4x

-8x+2y=2
-8x+2(4+4x)=2
-8x+8+8x=2
0=-6

An employee makes an hourly rate plus any tips they earn. This tip employee made a total of $400 by working 28 hours last week. If $253 of their total earnings was their tips, what is their hourly rate of pay?

Answers

To find the answer we must remove the tips amount from the total amount, and then divide what remains by the numbers of hours he worked. So we have: HourlyRate = (400 - 253) / 28 <=> HourlyRate = 147/28 <=> HourlyRate = $5.25

Katrina's mother is 2 inches shorter than her father, Katrina is 2 inches shorter than her mother, and Katrina's brother is 2 inches shorter than Katrina. Which best represents the change in height from Katrina's father to her brother?a. –8 inches
b. –6 inches
c. 6 inches
d. 8 inches

Answers

The answer would be B. Let's say Katrina's father was 10 inches tall. Subtract 2 inches to measure Katrina's mother's height, subtract another 2 inches to measure Katrina's height. Finally, subtract another 2 inches to measure Katrina's brother's height. Add all the negative 2s together in order to get -6. That is the difference between Katrina's father's height and her brother's height.

Answer:

B. -6 inches
