Answer:3rd option s=37


Step-by-step explanation:

See Ara and Evalyn are collecting stamps.

It is given that Ara has twice of 12 less than the stamps Evalyn has.

And we are given that total no. of stamps is 87.

So, our equation becomes,

2(S - 12) + S = 87

Where 'S' is no. of stamps Evalyn has.

Solving for S, we get,

S = 37

So , first we get to know is Wilmer's equation is incorrect because he has not added no . of stamps Evalyn has which is S

So option 3 is correct

We can also calculate the no. of stamps Ara has which is

2(37 - 12)

= 50

Hope it helps!!!

Answer:

The third option is the correct answer

The correct equation is,2(s - 12) + s =87

s= 37

Step-by-step explanation:

It is given that Ara and Evalyn are collecting stamps

Ara has twice as many stamps as 12 less than the number of stamps Evalyn has.

Together they have total 87 stamps.

<u>To find the correct equation </u>

Let s be the number of stamps in Evalyn.

The number of stamps in Ara = 2(s - 12)

They together have 87 stamps

Therefore the equation become,

2(s - 12) + s = 87

<u>To find the value of s </u>

2(s - 12) + s = 87

2s - 24  + s= 87

3s = 111

s = 37

Therefore the correct answer is 3rd option.

Y=2x +1 x=3. how do I find the Y in each equation
fiasKO [112]
Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation

If I'm right, then the process is

Y=2(3)+1 (putting 3 in place of x)

Y=6+1

Y=7

Which makes 7 your answer

An airplane travels 290 km between Austin and Dallas in 1 h 15 min. What is it’s average speed?
aniked [119]

The average speed of the plane between Austin and Dallas is 232 kmph

<u>Solution:</u>

Given that,

Total distance traveled by airplane = 290 km

Time taken for travel between Austin and Dallas = 1 hour 15 minute

Let us convert the time taken to hours

\begin{array}{l}{1 \text { minute }=\frac{1}{60} \text { hours }} \\\\ {15 \text { minutes }=\frac{15}{60}=\frac{1}{4}} \\\\ {\text { 1 hour } 15 \text { minutes }=1 \frac{1}{4} \text { hours }=\frac{1 \times 4+1}{4}=\frac{5}{4} \text { hours }}\end{array}

<em><u>The average speed is given as:</u></em>

\text { Average speed }=\frac{\text { total distance }}{\text { total time taken }}

Plugging in the values, we get,

\text { Average speed }=\frac{290}{\frac{5}{4}}=\frac{290}{5} \times 4=232

Hence the average speed is 232 kmph
