Seven less than two times a number is 29.

Alexxx [7]

2x-7=29

"Seven less than" => minus 7.
"Two times a number" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,

-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)

Solve for x A) 42 B) 40 C) 45 D) 38

alexgriva [62]

Answer:

x = 40

Step-by-step explanation:

Using similarity theorem, we have the following:

$\frac{24}{24 - 15} = \frac{x}{x - 25}$

Solve for x

$\frac{24}{9} = \frac{x}{x - 25}$

Cross multiply

$24(x - 25) = x(9)$

$24x - 600 = 9x$

Subtract 24x from each side

$- 600 = 9x - 24x$

$- 600 = -15x$

Divide both sides by -15

40 = x

x = 40
