Write the value of a after operation of the following assignment expression, and let a = 12 (1)a+=a (2)a-=2 (3)a*=2+3 (4)a/=a+a (5) A% = (n% = 2), the value of n is equal to 5 (6)a+=a-=a*=a

Write the value of a after operation of the following assignment expression, and let a = 12 (1)a+=a (2)a-=2 (3)a*=2+3 (4)a/=a+a (5) A% = (n% = 2), the value of n is equal to 5 (6)a+=a-=a*=a

(1)a+=a——a=24.
(2)a-=2——a=10.
(3)a*=2+3——a=60.
(4) A / = a + a -- a = 0 (when a is an integer)
(5) A% = (n% = 2), the value of n is equal to 5 -- a = 0
(6)a+=a-=a*=a——a=0.

If the following definitions int m = 5, y = 2;, then the value of y after the expression y + = y - = m * = y is

This connection operation, in fact, is very simple, operation order to know ol!
The operation sequence is from right to left. First, m * = y is 10, then y - = 10 is - 8, and finally y + = - 8 is - 16. It's so simple. I hope it can help you

1、 If a is an int variable and the initial value of a is 6, then the calculation expression a + = a - = a * a; the value of the latter a is []. 2

I have a problem with my question. I'll bring it up again later. I'm sorry

F (x) = 2 times x times LNX, G (x) = - x ^ 2 + ax-3, if x on (0, positive infinity) f (x) - G (x) is less than or equal to 0, the range of a is constant

2xlnx + x ^ 2-ax + 3 = 2lnx + X + 3 / X is constant (0, positive infinity), that is, the maximum value of a > = (2lnx + X + 3 / x). Let s (x) = 2lnx + X + 3 / X get s' (x) = 2X + 1-3 / x ^ 2, let s' (x) = 0 get x = 1 or - 1 / 3 (rounding) get the maximum value when x = 1, so a > = 4

How much less is 5 / 12 of 1.2 than 40% of 40
What is the sum of 25% of 3.12 plus 3 / 4 divided by 3 / 8?
The sum of 4.36 and 50 is 25% of a number. What is the number

40*40%-2*5/12=91/6
4.5/(85%-2/5)=10
12*25%+3/4/3/8=5
(36+50)/25%=344

A new operation is defined for rational numbers x and Y: X * y = ax + by + 5, where a and B are constants. Given that 1 * 2 = 9, (- 3) * 3 = 6, find the value of a, B, 2 * 7

It is known that when x = 1, y = 2, ax + by + 5 = 9, i.e. a * 1 + b * 2 = 4, i.e. a + 2B = 4 ①; when x = - 3, y = 3, ax + by + 5 = 6, i.e. - 3 * a + 3 * b = 1, i.e. 3a-3b = - 1 ②. By combining ① and ②, we get a = 10 / 9, B = 13 / 9. Then 2 * 7 = 2 * a + 7 * B + 5 = 2 * (10 / 9) + 7 * (13 / 9) + 5 = 156 / 9 = 52 / 3

How many meters is 40 meters 60 centimeters minus 20 decimeters

20 decimeters = 2 meters
40 m 60 cm - 2 m = 38 m 60 cm

As shown in the figure, in the triangle ABC, the angle B equals 90 degrees
 

It is proved that the connection AE ∵ de ⊥ AC ≌ Δ Abe and Δ ade are right triangles ∵ AB = ad, AE = AE ≌ Abe ≌ Δ ade ≌ de = be ∵ AB = BC ∵ a = ∠ C = 45 & # 186;
