Each letter's position in the alphabet is equal to the sum of the two numbers before it. For example, E is the 5th letter of the alphabet, and 2+3=5. I is the 9th letter of the alphabet, and 4+5=9. Thus, since 6+8=14, the next letter will be the 14th letter of the alphabet. This is the letter N.
Solution of system of linear equation y = 2x – 4 and 3x - 2y = 8 is x = 0 and y = -4
<h3><u>Solution:
</u></h3>
Need to determine solution of following system of linear equation
y = 2x – 4 ------(1)
3x - 2y = 8 ------(2)
If we observe the equation (1), we can say that we are having value of y in terms of x. so substitution method is the best approach to solve the above system of linear equation.
In substitution method, we will substitute value of y in equation (2) in terms of variable x from equation (1)
On substituting y = 2x – 4 in equation (2) , we get equation in one variable that is x which is as follows
3x – 2 (2x – 4 ) = 8
=> 3x – 4x + 8 = 8
=> -x = 8 – 8
=> x = 0
On substituting x = 0 in equation (1), we get
y = 2 x 0 – 4
=> y = -4
Hence solution of system of linear equation y = 2x – 4 and 3x - 2y = 8 is x = 0 and y = -4
Let the 2 numbers be x and y
x+ y = 35
let the larger number be x
3x = 4y
y = 3x/4
so,
x + 3x/4 = 35
7x/4 = 35
x/4 = 5
x = 4*5 = 20
so the larger number is 20.
We have been given that :-
The length of a parasite in experiment A is
The length of a parasite in experiment B is
Let us write the the length of the parasite in experiment A in the exponent of -3.
Clearly, the length of parasite in experiment A is greater than the length of parasite in experiment B.
The difference in the length is given by
Therefore, the length of the parasite in experiment A is inches greater than the length of the parasite in experiment B.
