How to solve the equation: 60% x + 25 = 40 and 38-50% x = 14 Urgent need for answers, do not give answers directly, the process also needs to be improved

60%X+25=40
60%X=15
X=15/60%
=25
38-50%X=14
50%X=24
X=24/50%
=48

Solve the equation 40-60% x = 25 fast!

40-60%x=25
0.6x=40-25
0.6x=15
x=15÷0.6
x=25

Solution equation: 1.60% + 25 = 402. X-10% x = 183. X + 30% x = 524. (1-25%) x = 36

(1)60%X+25=40.6X=4-25=-21X=-21/0.6=-35(2)X-10%X=18X-0.1X=18(1-0.1)X=18X=18/(1-0.1)=20(3)X+30%X=52X+0.3X=52(1+0.3)X=52X=52/(1+0.3)=40(4)(1-25%)X=36(1-0.25)X=360.75X=36X=36/0.75=48

Solve the equation. 40 + 40% x = 60 (1 + 20%) x = 72 3x + 25% = 13

40+40％x=60
0.4x=60-40
0.4x=20
x=20/0.4
x=50
（1+20％)x=72
1.2x=72
x=72/1.2
x=60
3x+25％=13
3x+0.25=13
3x=13-0.25
3x=12.75
x=12.75/3
x=4.25

ABCD multiplied by 9 equals DCBA a =? B =? C =? D =?
It's better to say the process

Because 9b can't carry, so B can only be 1 or 04. Suppose B is 1,9c + 8 and 1,9 * C and 3, so C is 7, but c * 9 can't carry, so B can only be 05, 10c9 * 9 = 9c01,9

If the ordinate of the intersection of the image of the first-order function y = 3x + m and the inverse scale function y = M-3 / X is 6, then M=____

Let the coordinates of the intersection be (x, 6)
3x+m=6 (m-3)/x =6
The elimination of X leads to M = 5

Cut a cylinder into a cuboid with the largest volume. The cuboid volume is 34.2 cubic centimeters less than the cylinder volume. If the cylinder is cut into a cone with the largest volume, what is the volume of the cone

The cuboid with the largest volume is a cuboid with the height of the cylinder as the height and the bottom as the square. Suppose the radius of the bottom is 1, and the area ratio of the inscribed square to the circle is 2:3.14

How to get the formula of polar coordinate area element

D θ is the increment of polar angle θ in polar coordinates
The area s is approximately equal to the area of the sector = 1 / 2 * R ^ 2D θ (where R is the polar longitude and D θ is the center angle of the circle)

Please help me to convert Mu and M2
Excuse me 600 mu is how many square meters? 1710000 square meters is how many mu? Want a result

600 mu = 400000 M2 = 40 ha
