X/2 + 3/2 < 5/2 give solution ​

Mathematics

Nataly [62]3 years ago

Start with

\dfrac{x}{2}+\dfrac{3}{2}

Multiply the whole equation by 2. Since 2 is positive, we don't need to switch the inequality sign:

x+3

Subtract 3 from both sides:

x

What is the next value 4d 7g 10j 13
bearhunter [10]
13m 16p

Add three to every number next as well as move up three letters.

For example:
1A is the starting point.
To get from 1A to 4D you add three.

1 + 3 = 4
A to get to D is three letters up.
A b c D

Same thing for 4D to get to 7G.

4 +3 = 7
D to get to G
D e f G

Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.

If you're trying to find the next equation to the puzzle (16p) is your answer.

Hope this helped!:)

When a particular mass-spring system is started by stretching the spring 3 cm, one complete oscillation takes 4 seconds.
11Alexandr11 [23.1K]

Answer:

A. 5.16 s.

B. 5.66 s.

Step-by-step explanation:

A.

For a simple harmonic motion,

T = 2pi (sqrt * (l/g))

Given:

L1 = 3 cm

T1 = 4 s

L2 = 5 cm

T2 = ?

4 = 2pi*sqrt(3/g)

g = 7.4

At, L2,

T2 = 2pi*sqrt(5/7.4)

= 5.16 s.

B.

M1 = M1

M2 = 2*M1

For a simple harmonic motion,

T = 2pi (sqrt * (m/k))

4 = 2pi (sqrt * (M1/k))

M1/k = 0.405

Inputting the above values,

T2 = 2pi (sqrt * (2*M1/k))

= 2pi (sqrt * (2 * 0.405))

= 5.66 s.

suter [353]
2.1S + 4.8H = 2808
H = 2S

2.1S + 4.8(2S) = 2808
2.1S + 9.6S = 2808
11.7S = 2808
S = 2808/11.7
S = 240

H = 2S
H = 2(240)
H = 480

so the standard version (S) has 240 downloads and the high quality version (H) has 480 downloads
