Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER

Answers

Answer:

[tex]xy=wz[/tex]

Step-by-step explanation:

Given that:

Speed of Wilmer up the hill = [tex]y[/tex] km/min

Time taken up the hill = [tex]x[/tex] minutes

Speed of Wilmer down the hill = [tex]z[/tex]  km/min

Time taken up the hill = [tex]w[/tex] minutes

Distance can be calculated by multiplying the Speed with Time i.e.

The formula for distance is given as:

[tex]Distance = Speed \times Time[/tex]

Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]

Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]

It is well known that, the distance up the hill and down the hill will be same.

Putting both the values equal, we get:

[tex]xy=wz[/tex]

Answer:

xy=wz

Your brother has $2000 saved for a vacation. His airplane ticket is $637. Write and solve an inequality to find how much he can spend for everything else.

Let x be the amount your brother can spend. Subtracting the cost of the plane ticket from savings, we have:

how to find the value of x in a triangle (5x-11)°, (2x+20)°, (11x-63)°

Answers

Answer:

x=13

Step-by-step explanation:

Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.

So, (5x-11) x (2x+20) x (11x-63) = 180.

Now, take away the parenthesis and add up all the like terms.

This should = 18x-54 = 180.

Now solve like you regularly would. Add 54 on both sides which equals,

18x=234. Now, divide 18 on both sides.

x = 13.

Hope this helps.

Answer:
x=13

Explanation:
All the angles in a triangle add up to 180 degrees, and this is true for every and any triangle. Knowing this, we can set up this equation and solve:

(5x-11)+(2x+20)+(11x-63)=180
1) Open up parentheses
5x-11+2x+20+11x-63=180
2) Combine like terms
5x+2x+11x-11+20-63=180
18x-54=180
3) Add both sides by 54
18x-54+54=180+54
18x=234
4) Divide both sides by 18
18x/18=234/18
x=13

I hope this helps!

Answer:

6 times

Step-by-step explanation:

'one' 50 cents, other 10 cents

If you get 50 cents you have to roll other number 5 times to minus 50 cents (50 divided by 10 is 5)

because they got nothing after roll so if they get a cents they have to minus it rolling other number

So if you divide 30 (the number of rolling) by 5 (the number of times to minus 50 cents) so the answer will be 6

Answers

9514 1404 393

Answer:

  6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

  6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

  (49 1/2)/(8 1/4) = (99/2)/(33/4)

  = (99/2)(4/33) = (99/33)(4/2)

  = (3)(2) = 6

Answer:

 6

Step-by-step explanation:

We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:

 6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2

Sue can make 6 bracelets.

_____

You can also divide the total length of chain by the amount per bracelet:

 (49 1/2)/(8 1/4) = (99/2)/(33/4)

 = (99/2)(4/33) = (99/33)(4/2)

 = (3)(2) = 6

Step-by-step explanation:

equation: y = x - 6 + x^2

(6,0) (7,1) (8,4) (9,9)

I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.

5x + 55= 2x+ 100
Please answer.

Answers

Answer:

x = 15

Step-by-step explanation:

Given

5x + 55 = 2x + 100 ( subtract 2x from, both sides )

3x + 55 = 100 ( subtract 55 from both sides )

3x = 45 ( divide both sides by 3 )

x = 15

X=15
Subtract 2x from Both sides and subtract 55 from both sides so that’ll be 3x=45 divide both sides by 3 and get 15
