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

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

Answers

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:
x <= 2000 - 637
x <= 1,363

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
