The solution of equation 3x-5 = 25 is 10. Why is the answer wrong?

The solution of equation 3x-5 = 25 is 10. Why is the answer wrong?

3x-5=25
Solution: 3x = 25 + 5
x=30÷3
x=10
So x = 10 is the solution of the equation

The solution of equation 2x-3 = 3x-x + 2 is
The solution of equation 2x-3 = 3x-x + 2 is

This question is wrong

How to solve the equation of X with the method of piecewise zeros: 15 + | 2x + 3 | - 2 | - 3x | = 0?
It is better to attach how to solve the equation with the method of piecewise zeros
What I don't understand is: how to classify, discuss and list after segmentation?

When 2x + 3 and 2-3x are both greater than 0, we can get: - 3 / 2 〈 x 〈 2 / 3, remove the absolute value sign as: 15 + 2x + 3-4 + 6x = 0, then we can get x = - 14 / 8, which is not the correct answer. 2

On the collocation of preposition and way
______ he didnt help me with my work.Instead ,just________ .
A.In a way,in my way B.On a way,on the way
C.In the way,on the way D.By the way ,on my way
It's better to explain all the above phrases

Wait for me to make it clear!
______ he didnt help me with my work.Instead ,just________ .
A.In a way,in my way B.On a way,on the way
C.In the way,on the way D.By the way ,on my way
Choose a
To some extent, he didn't help me. On the contrary, he got in my way
Choice analysis:
A. In a way, to some extent; a little; very excited = in some degree, in part
In my way = in the way
B. On a way is not a fixed phrase. It's just to increase the difficulty
On the way / on one's way
2. Go, in progress, in In the process of; about to become; about to do (something)
C. In the way, on the way
D. By the way
By the way, = in transit, on one's way to
On my way

The numerator and denominator of 46 / 73 are subtracted by the same number at the same time, and the result is 11 / 20. The subtracted number is ()

The correct answer is 13. Upstairs, it's all wrong and speechless,

Is the + adjective singular or plural
Is the predicate singular or plural

You are asking about the category of subject predicate agreement
When nominalized adjective is used as subject, it depends on the specific situation of the subject
As plural
The wounded were sent home.
The wounded were sent home
The old are taken good care of here.
The old people here are well taken care of
Think of it as singular
The true is to be distinguished from the false.
True and false must be distinguished
The accused was punished to prison.
The accused was sentenced to prison

Let a = (2, - 1), B = (4,4), C = (- 3,2), then (a-2c) * b =?
Multiply the abscissa and ordinate of C by 2, and then subtract the abscissa and ordinate of 2C from the abscissa and ordinate of A
And then we get the coordinates and the coordinates of B, the abscissa times the abscissa plus the ordinate times the ordinate
Or so? A-2c = (8, - 3)
(a-2c).b=8X4-3X4=20
How does a-2c work out? (a-2c = (2 - (- 6), - 1-4) = (8, - 5) so?

（a-2c=（2-（-6）,-1-4）=（8,-5)
(a-2c).b=8X4-3X4=20
This is correct, you look good next book, is the vector addition and subtraction and quantity product two concepts, nothing else

Is rope skipping a verb or a noun
well,

A verb phrase can be used as a noun in a sentence
Skiping rope is my hobby

As shown in the figure, in △ ABC, D and E are the points on AB and AC respectively, and BD = CE, m and N are the midpoint of be and CD respectively. Do the lines passing through Mn intersect AB at P and AC at Q, and the lines AP and AQ are equal? Why?

AP = aq. The reasons are as follows: as shown in the figure, take the midpoint h of BC, connect MH, NH. ∵ m, h is the midpoint of be, BC, ∥ MH ∥ EC, and MH = 12ec. ∵ n, h is the midpoint of CD, BC, ∥ NH ∥ BD, and NH = 12bd. ∵ BD = CE, ∥ MH = NH. ∥ HMN = ∥ HNM; ∥ MH ∥ EC, ∥ HMN = ∥ PQA, similarly, ∥ HNM = ∥ QPA. ∥ Apq is isosceles triangle, ∥ AP = aq
