cho mik kb vs bn nha ^_^

 

a: \(\Leftrightarrow\left(5x+\dfrac{3}{2}\right):\dfrac{8}{15}=\dfrac{25}{12}-\dfrac{5}{6}=\dfrac{25}{12}-\dfrac{10}{12}=\dfrac{15}{12}=\dfrac{5}{4}\)

\(\Leftrightarrow5x+\dfrac{3}{2}=\dfrac{5}{4}\cdot\dfrac{8}{15}=\dfrac{40}{60}=\dfrac{2}{3}\)

\(\Leftrightarrow5x=\dfrac{2}{3}-\dfrac{3}{2}=\dfrac{4-9}{6}=\dfrac{-5}{6}\)

hay x=-1/6

b: \(\Leftrightarrow\dfrac{1}{4}\left(2-\dfrac{1}{2}x\right)=\dfrac{5}{2}-\dfrac{1}{4}=\dfrac{10}{4}-\dfrac{1}{4}=\dfrac{9}{4}\)

=>2-1/2x=9

=>1/2x=-7

hay x=-14

c: \(\Leftrightarrow\left(x-7\right)^2=144\)

=>x-7=12 hoặc x-7=-12

=>x=19 hoặc x=-5

d: \(\Leftrightarrow4x+2=3x-15\)

hay x=-17

e: =>1/6x=-4

hay x=-24

(-2) + 4 + ( -6) + 8 + (-10) + 12 + (-14) + 16 + (-18) + 20

=[(-2) + 12] + [4+(-14)] + [(-6)+16] + [8+(-18)] + [(-10)+20]

=    10        +     (-10)    +    10       +    (-10)    +    10

=(10 +10 +10) + [(-10) + (-10)]

=    30             +      (-20)

=              10

1 1/4 tấn=5/4 tấn=0,25 tấn=250kg

2 2/5 tạ=12/5 tạ=2,4 tạ=240 kg

Tổng của 1 1/4 tấn+2 2/5 tạ là:

    250+240=490(kg)

                   Đáp số:490 kg
