I’m not sure, you’re not elaborating enough to this equation. Are you sure you’re not missing a phrase of some sort?

What is the value of x? Enter your answer in the box. __mm

You can set up a ratio as follows:
$\frac{x-22}{87.5}= \frac{22}{77}$

Solve for x by cross-multiplying:
$(x-22)(77) = (87.5)(22)$
$x = \frac{(87.5)(22)}{77} + 22= 47.01$

Since we need the answer in mm and right now we have it in feet, we need a conversion ratio. After googling it, the conversion ratio is: 1ft = 304.8mm
$47.01(304.8) = 14326.64$

So, the answer is 14326.64 mm.

10. 5(3-9b) = 3(-15b – 2)

olga2289 [7]

Answer:

No Solution

Explanation:

5(3 - 9b) = 3(-15b – 2)

Expand

5(3 - 9b): 15 - 45b

3(-15b - 2): -45b - 6

15 - 45b = -45b - 6

Subtract 5 From Both Sides

15 - 45b - 15 = -45b - 6 - 15

Simplify

-45b = -45b - 21

Add 15b To Both Sides

-45b + 15b = -45b - 21 + 15b

Simplify

0 = -21

No Solution

"he residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 4 to 5. If there were 3

charle [14.2K]

Answer: 5742

================================================

Work Shown:

x = number of yes votes

(number who said yes)/(number who said no) = 4/5

x/3190 = 4/5

5x = 3190*4 .... cross multiply

5x = 12760

x = 12760/5 ... divide both sides by 5

x = 2552

There were 2552 people who voted yes

The total number of votes is 2552+3190 = 5742
