Answer:
The value of x is 5.
The value of y is 4.
Step-by-step explanation:
From the figure, the lengths of the lines with equal number of markings are equal.
So, we will have the length of 7x - 4 = 31.
We solve for 'x'.
We get: 7x = 35
⇒ x = 5
Similarly, 4y + 8 = 24
⇒ 4y = 24 - 8
⇒ 4y = 16
⇒ y = 4
Therefore, the value of x = 5 and y = 4.
Hence, the answer.
Force is:F = k * ( q1 * q2 ) / r²Therefore:k * ( 2.35 * 1.96 ) / r² = k * ( 4.06 * 2.11 ) / ( 2.26 )² / : k4.606 / r² = 8.5666 / 5.10768.5666 r² = 4.606 * 5.1076r² = 23.5256 : 8.5666r² = 2.7462r = √2.7462Answer:r = 1.66 pm
Answer:
hi dont report me we are friends can i get brainliest plzz?
Step-by-step explanation:
We will call the first number n, and the second number x.
3n-x=118
2n+x=147
Now, solve one of the equations for x.
x=147-2n
Then, substitute this into the other formula for x.
3n-(147-2n)=118
Next, solve for n:
3n-147+2n=118
5n=265
n=53
^^^That's your first number.
Lastly, plug in 53 for n into either equation to solve for x.
2(53)+x=147
106+x=147
x=41
^^^This is your second number.
