第1題, 我應該可以幫到你~

4c-60=16c+33
4c-16c=33+60
-12c=93
c=-7.75

2.Mary spends $825 to buy a T-shirt and a coat.The price of the T-shirt is $258 cheaper than half of the price of the coat.How much is the coat?
Mary 用左 $825 買左一件 T-shirt 和一件 coat . T-shirt 既價錢係 coat既價錢既一半再便宜$258 . 問 coat 係幾多錢?

設 coat既價錢 = a

(a/2-258)+a=825

a = 答案

3.John had $316 and Peter had $120. Then John gave more some money to Peter so that they had equal amount of money.How much did John give Peter?

John 有 $316 和 Peter 有 $120 . John 跟住送左d錢比 Peter . 之後 John 和 Peter 一樣有咁多錢 . 問 John 比送左幾多錢比 Peter ?

$120+$a = $316-$a

a = 答案

應該兩題都錯 = ="

Mary 用左 $825 買左一件 T-shirt 和一件 coat . T-s ...

第3題錯左

解:
let jhon gave peter $x
$316-$x       = ($316+$120)/2
$316-$x       = $436/2
$316-($436/2) = $x
$316-$218    =  $x
               $x=$98

-33-點解我計到吾同ge=  =..
我係甘計ga..:
(2分之x - 258)+x=825
         2分之x+x=825+258
         2分之3x=1083
                  3x=1083乘2
                  3x=2166
                     x=2166除3
                     x=$722
不過我表姐教ga...
無理由件coat甘平ga...
$98就買到...流野- -

John果題都ok易ge...
($316-$120)除2
=196除2
=$98

超姐...
我係甘計:
a+[(a+258)*2]=825
a+(2a+516)=825
a+2a+516=825
3a=825-516
3a=309
a=103

唔知啱唔啱...

作者: ●siu_y_an§ 時間: 2007-8-12 06:41 PM

第一題...
[1-(8分之3+8分之5乘3分之1)]分之30
=1-(8分之3+24分之5)分之30
=1-(24分之9+24分之5)分之30
=1-24分之14分之30
=24分之24-24分之14 分之30
=24分之10分之30
=3乘24
=72

第二題
x分之8+36=18
x分之8+36-36=18-36
x分之8=-18
x分之8乘x=-18x
-18分之8=x
x=-9分之4
