sattari [20]

Answer:

24 red marbles

Step-by-step explanation:

Ok, why not let R = number of red marbles.

The first sentence says:

3 * R = (33 and 1/3) % * R + 64

3R = 100/3 %*R + 64

3R = (1/3)*R + 64

9R = R + 192

8R = 192

R = 24 red marbles

Shoot your shot! When Nick shoots a basketball, he either sinks the shot or misses. For each shot Nick sinks, he is given 5 poin

Misha Larkins [42]

Answer:

Nick sank 8 shots

Step-by-step explanation:

* Lets explain how to solve the problem

- Assume that Nick sinks x shots and misses y shots

- Nick attempts a total of 28 shots

- That means he sinks and misses 28 shots

∴ x + y = 28 ⇒ (1)

- His father give him 5 points (+5) for every sank shot and takes away

2 points (-2) for every missed shot

- That means his score calculated by adding (the number of sank shots

multiplied by 5) and (the number of missed shots multiplied by (-2))

- Nick ends up with zero points

∴ 5x + (-2)y = 0

- Remember: (+)(-) = (-)

∴ 5x - 2y = 0 ⇒ (2)

* Now we can solve the two equations by elimination method to find

the number of sank shots

- Multiply equation (1) by 2 to eliminate y

∴ 2x + 2y = 56 ⇒ (3)

- Add equations (2) and (3)

∴ 7x = 56

- Divide both sides by 7

∴ x = 8

∵ x represents the number of sank shots

∴ Nick sank 8 shots
