Given:
X: The blue marbles.
3X: The red marbles.
A box contains 144 marbles.
SOLVING:
X + 3X = 144
4X = 144
X = \frac{144}{4}
X = 36 ===> The blue marbles.

If there are 3 times as many red marbles as there are blue marbles:
3(36) = 108 ===> The red marbles. SOLUTION

TESTING:
36+108=144
\boxed{144}=\boxed{144}\quad\checkmark\ The\ value\ is\ correct.
GOOD LUCK...!!!

The pair of values below is from a direct variation. Find the missing number.
NISA [10]

Answer:

The answer is 2.

2  since 6/4=3/2

Step-by-step explanation:

Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)

If y=kx then y/x=k.

So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.

So we are going to solve this proportion:

\frac{6}{4}=\farc{3}{x}

Again I put y/x from each point. They should have same ratio because this is a direct variation.

Cross multiply:

6(x)=4(3)

6x=12

Divide boht sides by 6:

x=\frac{12}{6}

x=2
