Answer:

If JL = 16, we will get JK = 7

Option A is correct option.

Step-by-step explanation:

We are given:

K is between J and L

JK = 3x – 5, and KL = 2x + 1.

IfJL = 16, what is JK

We know that K is between J and L it means it divides JL into JK and KL equally or we can say that adding JK and KL we can get JL

So, We can write:

JL = JK + KL\\16=3x-5+2x+1

Solving the expression we can find first value of x and then value of JK

16=3x-5+2x+1\\16=5x-4\\16+4=5x\\20=5x\\x=\frac{20}{5}\\x=4

So, we get x = 4

Now, put the value of x in JK=3x-5 to get value of JK

JK = 3x-5\\JK=3(4)-5\\JK = 12-5\\JK=7

So, if JL = 16, we will get JK = 7

Option A is correct option.

A bicycle is traveling at 16 miles per hour. How many feet will it cover in 35 seconds? Round your answer to the nearest tenth o
ch4aika [34]

A  bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.

It is required to find How many feet will it cover in 35 seconds.

<h3>What is conversion?</h3>

conversion is the process of changing the value of one form to another for example inches to millimeters, or liters to gallons. Units are used for measuring length, measuring weight, measuring capacity, measuring temperature, and measuring speed.

Given that:

1 hour = 60min×60sec = 3600 sec

1 miles = 5280 feet

16 miles = 16×5280ft = 84480 ft

3600sec ................. 84480  ft

35sec ................................ x ft

x = 35×84480/3600

=2956800 /3600

= 821.33 feet.

Hence, a bicycle is traveling at 16 miles per hour it covers 821.33 ft in 35 seconds.

What is the value of 36X negative Y over to when X equals three and Y equals -6
Rus_ich [418]

<u><em>Note:</em></u>

<em>Your question is a little unclear. But, from my understanding, I assume you may be asking the evaluation of the expression 36x - y when x = 3 and y = -6.</em>

<em>so I will solve based on my assumption which anyways would clear your concept.</em>

Answer:

The value of 36x - y when x = 3 and y = -6 will be: 114

Step-by-step explanation:

Given

Assuming the expression

36x - y

To Determine

Evaluate 36x - y when x = 3 and y = -6

Given the expression

36x - y

substitute x = 3 and y = -6 to evaluate the expression

36x-y= 36(3) - (-6)

            = 108+6

            = 114

Therefore, the value of 36x - y when x = 3 and y = -6 will be: 114

NNADVOKAT [17]

Answer:

<h2>37/9</h2>

Step-by-step explanation:

<h3>we have</h3>

<h3>3.77777... :- is a repeating decimal</h3>

<h3>Let</h3>

<h3>x = 3.7...</h3>

<h3>so</h3>

<h3>10x =37.7...</h3>

<h3>10x - x = 37.7... -3.7...</h3>

<h3>9x=34</h3>

<h3>x= 34/9</h3>

<h3>convert to mixed number</h3>

<h3>34/9=(27/9)+(7/9)=3+(7/9) =37/9</h3>

<h3> I hope this may help you.</h3>
