What is the solution set of equation 3x-5 = 0?

What is the solution set of equation 3x-5 = 0?

x=5/3

7x+0.3x=3.65

7.3x=3.65
x=0.5

Equation 9 ^ x + (M + 1) ^ 3x + 4 = 0 has solution
Equation 9 ^ x + (M + 1) ^ 3x + 4 = 0 has a solution to find the value range of M
- -

Let 3 ^ x = t, the original square city can be transformed into T ^ 2 + (M + 1) t + 4 = 0, which is a problem of finding the range of quadratic equation with one variable, where the domain of definition is t greater than zero (M + 1) ^ 2-4 * 4 > 0 - (M + 1) > 0, and the final result is m

X-2 / 3x = 2 / 9 solved by equation

X-2/3x=2/9 1/3x=2/9 x=2/3

It is known that two straight lines L1: (3 + m) x + 4Y = 5-3m, l2:2x + (M + 5) y = 8. When m is different, 1) intersect 2) parallel 3) vertical 4) coincide

L1: (3 + m) x + 4Y = 5-3m, L2: 2x + (5 + m) y = 8 L1: (3 + m) x + 4Y = 5-3m = = > y = [5-3m - (3 + m) x] / 4 L2: 2x + (5 + m) y = 8 = = > y = (8-2x) / (5 + m) 1. Intersection [5-3m - (3 + m) x] / 4 = (8-2x) / (5 + m) leads to m ≠ - 1, - 7 2. Parallel K1 = K2, (3 + m) / 4 = - 2 / (5 + m) leads to M = - 1, -

How to solve 3-1 / 3x = 2-1 / 2x?

Change x to one side
1/2x-1/3x=2-3
1/6x=-1
x=-6

The carton factory processes the carton. The carton is 20cm long, 6cm wide and 6cm high. How many square meters of cardboard does it need to make 1000 such cartons?

(20 * 6 * 2 + 6 * 6 * 4) * 1000 = 384000 38.4 square meters

Nikola Tesla
What's his IQ

No more than 229. The highest is not him! I don't know, he was poor all his life, but his achievement is more outstanding than Edison. You can go to the encyclopedia to check him in detail

Given x + 1x = 2, then the value of XX2 + 3x + 1-xx2 + 9x + 1 is equal to___ ．

From x + 1 x = 2, the square of both sides is: x + 1 x = 2, the original formula = 1 x + 1 x + 3-1 x + 1 x + 9 = 55-1111
