$42 discount

210 - 42 = 168

Your total amount you would pay would be $168. The discount is $48.

Part A: Solve –vp + 40 < 95 for v. Show your work. Part B: Solve 8w – 3r = 45 for r. Show your work.

Darya [45]

Part a

-vp + 40<95

-vp +40-40 <95-40

-vp < 55

-vp/p < 55/p

-v< 55/p

(-1)(-v) < (-1) (55/p)

v< -55/p

Part b

8w-3r=45

8w-8w-3r = 45-8w

-3r = 45-8w

-3r/-3 = 45-8w/-3

What is the value of x?

prohojiy [21]

The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate. Also called "Abscissa" See: Coordinates.

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.
