So the number 1 is 120%, the number 3 is the unit "1", and the number 2 is 96%, so the water in the No.2 bucket is the least.
(2)
D is "1", C is 1/4, B is 1/3 of 1/4, D is 1/2, and A is1/of B.
1+1/4+112+1/24 = one and three eighths.
3960 divided by one and three eighths = 2880- d.
2880 times 1/4 = 720-C
720 times 1/3 = 240-B
240 times1/2 =120-a.
(3) the total amount of sugar is set to x.
(X+ 10) times 60%=(X+30) times 75%-30.
x = 90°
(90+ 10) times 60%=60 pieces-chocolate.
90-60=30 (block)-Toffee
Simple understanding of acute physical error analysis: when measuring electromotive force potential and internal resistance by voltammetry, the ammeter is connected outside the voltmeter range, E=U+I*r, and the voltage shared by the ammeter is not included in e, so the measured electromotive force value is less than the true value, while r=(E-U)/I, the electromotive force is less than the actual value, and so is the internal resistance. ...
Trigonometric function is urgent! Because c is already 90 degrees in the triangle problem.
So a+b=90 degrees. A and B are complementary angles.
Sina =co *** =cos(90-a).
The second problem is factorization, urgent 4a- 1+b? -4a？
=b？ -(4a？ -4a+ 1)
=b？ -(2a- 1)？
=(b+2a- 1)(b-2a+ 1)
How to solve the breach of contract? Urgent! You can't go to school to change the contract until you get the rejection letter from the company you broke the contract and the acceptance letter from the new company. Basically, the money for breaking the contract is indispensable. It's a problem that they don't cancel your contract now, because it usually takes five months to get a new agreement after breaking it. If you are sure, you can sign an agreement with the current company (the company's own agreement) first, and then change to a new agreement when the original company replies to your letter. As for their unauthorized modification of the contract, it is considered that they have breached the contract. You don't have to pay liquidated damages, depending on the other party's tough attitude. If it really doesn't work, agree to pay. 2000 is not much, but ours is 3000.
Help, math problem! Urgent! Solving the equation requires a clear process.
1.4*(0.8+X)=7.2
Remove brackets
3。 2+4X=7 .2
Mobile project:
4X=7 .2-3。 2
4X=4
X= 1
2.(X- 1.8)/2=205
Bilateral multiplication: 2
X- 1 .8=4 10
X= 1 .8+4 10
X=4 1 1 .8
3.0.4X-2* 1. 1=2
0。 4X=2+2 .2
0。 4X=4 .2
X X= 10/0.5
Two fractional equations. Urgent ~ ①3x/4+2/7=8
3x/4=8-2/7=54/7。
Multiply both sides by 28.
3x*7=54*4=2 16
X=2 16/2 1。
Then x=72/7.
①
1x/3+ 1x/2=5/8
x( 1/3+ 1/2)=5/8
5x/6=5/8
Multiply both sides by 24.
5x*4=5*3
That is 20x= 15.
Then x=3/4.
Urgent, ask some English questions. This is another sub-question. Please wait for the kind people to take their time.
Why do so many people in this society want to run away and not feed the horses?
Urgent! I TOUCH done can't shut down after waiting for the restart, restart the black rain boot, and then you can boot.

Urgent! WOW sideline study problem jewelry income is the highest among all majors at present.
Not only is the self-benefit effect great, but it can also be used as a way to make money.
The second one depends on your own preferences. PVE and PVP are better than engineering. Engineering gloves and shoes FM is very overbearing.
There is 1 FM, but the improvement is not great.
