What is the root of equation (x 5) (2x-1) = 0?

What is the root of equation (x 5) (2x-1) = 0?


The root of the equation is that each bracket is equal to 0
So X-5 = 0 or 2x-1 = 0
X = 5 or 1 / 2



When a is a, the root of the equation x + 2 / 4-2x + A / 6 = 1 is 0?
Because:
So:
Just one question,


When a is a, the root of the equation x + 2 / 4-2x + A / 6 = 1 is 0?
The process should be detailed
Because: x + 1 / 2-2x + A / 6 = 1
-X=1/2-a/6
Let x = 0,
Then a / 6 = 1 / 2
So: a = 3



If the sum of mx3yp and nxm + 1Y2 is 0, then M-N + 3p=______ .


The solution is: M = 2n = - 2p = 2, then M-N + 3P = 2 + 2 + 2 × 3 = 10



On tree planting day, the number of trees planted in class A is 20% more than that in class B, and the number of trees planted in class B is 10 more than half of that in class A. if there are x trees planted in class B, the number of trees planted in class A is 20% more than that in class B
1: Two different formulas with X are given to show the number of trees planted in class A
2: According to the meaning of the question, the equation with X as the unknown number is listed
3: The number of trees planted in class A and class B was 35 and 25 respectively


1.120%x (x-10)X2 2.120%x=(x-10)X2 3.120%x=(x-10)X2
1.2x=2x-20
-0.8x=-20
x=25
120%x=30

The sum of all integers whose absolute value is less than 2008 is______ .


All integers with absolute values less than 2008 are - 2007, - 2006, - 2005 The sum is - 2007 + (- 2006) + (- 2005) + +2005 + 2006 + 2007 = 0

There are three kinds of balls in the box. The ratio of the number of yellow balls to the number of red balls is 2:3, and the ratio of the number of red balls to the number of white balls is 4:5
Known yellow ball is 35 less than white ball, how many red balls?


Yellow: red = 2:3
Red: white = 4:5
The red ball appeared twice, which can be unified. Through the comparison, the yellow ball: red ball: white ball = 8:12:15
35 divided by (15-8) = 5
5 × 12 = 60



How many decimeters is 60 centimeters
