14 20

---- = ----- cross multiply

3x x-5

14(x-5) = 3x (20)

14x - 70 = 60x

-14x -14x

-70 = 36x

/36 /36

-70/36 = x

What do you add to 2 1/8 to make 4

barxatty [35]

Step-by-step explanation:

Let us add x to $2\frac{1}{8}$ to make 4.

$\therefore \: x + 2 \frac{1}{8} = 4 \\ \\ \therefore \: x + \frac{2 \times 8 + 1}{8} = 4 \\ \\ \therefore \: x + \frac{16 + 1}{8} = 4 \\ \\ \therefore \: x + \frac{17}{8} = 4 \\ \\ \therefore \: x = 4 - \frac{17}{8} \\ \\ \therefore \: x = \frac{4 \times 8 - 17}{8} \\ \\ \therefore \: x = \frac{32- 17}{8} \\ \\ \therefore \: x = \frac{15}{8} \\ \\ \therefore \: x =1 \frac{7}{8} \\ \\ \therefore \:1 \frac{7}{8} \: should \: be \: added \: in \: 2 \frac{1}{8} \: to \: \\ \: \: \: \: \: make \: it \: \: 4.$

Plz help with this question

AnnyKZ [126]

225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.

Yanka [14]

Answer:

x=47 feet

Step-by-step explanation:

Since angle VTY is congruent to angle VTK, segment TY bisects angle VTK. Since Y is on segment VK, between V and K, we can use the Angle Bisector Theorem, which states that:

$\frac{VY}{YK}=\frac{VT}{TK}$
