Answer:

10 + 6C

Step-by-step explanation:

C = the number of CDs Alyssa has

Alyssa has C CDs

Fran has five more than three times as many CDs as Alyssa.

Fran has 5 + (3 * C)

Fran has (5 + 3C) CDs

Jessica has twice as many CDs as Fran

Jessica has 2 * (5 + 3C) CDs

Jessica has 10 + 6C CDs

The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of
Snowcat [4.5K]

Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

x+y+z=855

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

x + y + z = 855

substituting y + z = x / 1.5 in the equation

x+\frac{x}{1.5}=855

Multiply both sides by 1.5

x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5

1.5x+x=1282.5

2.5x=1282.5

Divide both sides by 2.5

\frac{2.5x}{2.5}=\frac{1282.5}{2.5}

x = 513

Therefore, the value of x = 513

In the graph,

Amplitude = 1.5 units

Period = 180°

The x-intercepts are 40°, 140°, 220°, and 320°

<h3>Determining x-intercepts </h3>

From the question, we are to determine the amplitude, period and the x-intercepts of the given graph

Amplitude is the distance from rest to crest.

In the graph,

Amplitude = 1.5 units

Period is how long from crest to crest OR trough to trough

In the graph,

Period = 180°

x-intercepts refers to the points where the graph cuts the x-axis

In the graph,

The x-intercepts are 40°, 140°, 220°, and 320°
