15.5:4 = 2 + 4 x solution equation

15.5:4 = 2 + 4 x solution equation

I'm glad to answer your question
15.5:4 = 2 + 4 / X
15.5/4=2+x/4
x/4=3.875-2
x/4=1.875
x=4x1.875
x=7.5

Solving equation x + 1 / 3-1 / 5 = 7 / 15

x=7/15+1/5-1/3
x=7/15+3/15-5/15
x=(7+3-5)/15
x=5/15
x=1/3
I hope I can help you. Happy study

Solution equation: X-12 / 5 = 4 / 1 15 / 7 + x = 5 / 4 X-2 / 1 = 3 / 1

You seem to have misused '/', OK
Give you the results in words
1. X = two thirds
2. X = one third
3. X = five sixths

What is the meaning of factorization

To convert a polynomial into the product of several integers

The greatest common factor of a and B is 8, the least common multiple is 280, the known number a is 40, and the number B is tens

40/8=5
The greatest common factor of a and B is 8, so B is not a multiple of 5
The least common multiple is 280 / 5 = 56
B must also be a divisor of 56
56 / 8 = 7 is prime
So B could be 8 or 56
When B = 8, the least common multiple of a = 40 is not 280, it is not 40
B-56, the least common multiple is 280
So B = 56

If the - 1 power of a is greater than the - 1 power of 3, find the value range of real number a

In fact, you can easily find the answer by drawing a graph of y = 1 / X
a:(0,3)

5 / 6 of a number is 45, 2 / 3 of this number is (), 5 / 9 of a number is equal to 3 / 4 of B number, a number is 27, B number is
(). No formulation

5 / 6 of a number is 45, 2 / 3 of this number is (36)
5 / 9 of a is equal to 3 / 4 of B. A is 27 and B is 20

The teacher helped me to solve it. I thought for a long time. Let r = 3, N1, N3, N4 of the coefficient matrix of four unknowns of non-homogeneous linear equations be its three solution vectors
Where n 1 + N 2 = (1,1,0,2), N 2 + n 3 = (1,0,1,3), try to find the combined general solution of the non-homogeneous linear equation
Now I just don't know how to find that particular solution. That particular solution should be N1 + N3, but I don't know how to find it

So (N1 + N2) / 2, (N2 + N3) / 2 are all special solutions

Three masters process a batch of parts. Master a processes 13 parts in 20 minutes, master B processes 7 parts in 10 minutes, and master C processes 4 parts in 5 minutes. Whose work efficiency is high?

Master A. divide the number by time = efficiency. Master a is the highest
