Find the value of x in the figure below.
masya89 [10]

Answer:

6


Step-by-step explanation:

The figure inside the circle is symmetric.  Therefore, 3x + 5 = 5x - 7.  Solving for x, we subtract 3x from both sides and then add 7 to both sides.  This comes out to 2x = 12, meaning that x must be 6.

Mamont248 [21]

Answer:

The answer is 131 people

Step-by-step explanation:

I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.

Hopefully that helped lol

three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen
Marianna [84]

Answer:

Let x be the number.

Given the statement: Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen.

" sum of a number and four" translated to x + 4

"Three sets of a sum of a number and four" translated to 3(x+4)

"sum of seven times the same number and thirteen" translated to 7x + 13

then;

the expression for the given statement become;

3(x+4) + 7x + 13

Using distributive property: a\cdot (b+c) = a\cdot b + a\cdot c

3x +12 + 7x+ 13

Combine like terms;

10x + 25

Therefore, the simplified expression for Three sets of a sum of a number and four are added to the sum of seven times the same number and thirteen. is,  10x + 25
