What the sum of (5w-4)+(2w-1) show work

Bad White [126]

(5w - 4) + (2w - 1)

⓵

5w + 2w = 7w

5w + -1 = 5w -1

-4 + 2w = 2w - 4

-4 + -1 = -5

⓶

7w + 5w - 1 + 2w - 4 - 5

7w + 5w + 2w = 14w

-1 + -4 + -5 = -10

⓷

→ Your answer is : (5w - 4) + (2w - 1) = 14w - 10

There you go. I really hope this helped, if there's anything just let me know! :)

Help with this one? Please

netineya [11]

Answer:

x = 40

Step-by-step explanation:

The figure shows two similar triangles. Thus, the side lengths of similar triangles are proportional to each other. Therefore:

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

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

Cross multiply

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

$24x - 600 = 9x$

Subtract 24x from each side

$- 600 = 9x - 24x$

$- 600 = -15x$

Divide both sides by -15

$40 = x$

x = 40
