C. X= 5 5/7

Answers

the answer is c. x = 5 5/7

13 = 2f + 5
i don't know how to solve this

Answers

Simplifying13 = 2f + 5
Reorder the terms:13 = 5 + 2f
Solving13 = 5 + 2f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-2f' to each side of the equation.13 + -2f = 5 + 2f + -2f
Combine like terms: 2f + -2f = 013 + -2f = 5 + 013 + -2f = 5
Add '-13' to each side of the equation.13 + -13 + -2f = 5 + -13
Combine like terms: 13 + -13 = 00 + -2f = 5 + -13-2f = 5 + -13
Combine like terms: 5 + -13 = -8-2f = -8
Divide each side by '-2'.f = 4
Simplifyingf = 4

SO, f = 4

13 = 2 × 4 + 5

Yes, it's the same.

A bird leaves its nest and travels 14 miles per hour downwind for x hours. On the return trip, the bird travels 4 miles per hour slower and has 6 miles left after x hours.a. What is the distance of the entire trip?

miles

b. How long does the entire trip take? (In Hours Minutes and Seconds

Answers

1.5hr the distance of the entire trip
The time for the entire trip is 3.375 hours.
The total distance of the trip is 60 miles.

The total distance of the trip

The given parameters include;

The speed of the bird in the forward trip = 20 m/h
Time of motion = x
The speed of the bird in the backward trip in x hours = (20 - 4)m/h = 16 mi/h.
Distance remaining to complete the backward trip = 6 miles.

The time to complete each trip is calculated as;

distance = $speed $*$ time$

forward distance = backward distance

$&20 x=16 x+6 \n$

$&20 x-16 x=6 \n$

$&4 x=6 \n$

$&x=(6)/(4) \n$

$&x=1.5 h r$

The total time of the motion for the entire trip exists calculated as follows;

Time = time for forward + time for backward

$\text { time } &=1.5 \mathrm{hr} r_{\text {forward }}+1.5 \mathrm{hr} \text { backward }+\frac{6 \mathrm{mi}}{16 \mathrm{mi} / \mathrm{hr}} \text { backward } \n$
