Số cam bằng: 1: ( 1 + 1) = \(\dfrac{1}{2}\) ( tổng số cây)

Số xoài bằng: 1 : ( 1 + 1) = \(\dfrac{1}{2}\) ( tổng số cây)

Số cây chanh bằng: 1 - \(\dfrac{1}{2}\) - \(\dfrac{1}{2}\) = 0 (tổng số cây)

Số cây cam  bằng số cây xoài và bằng: 120 \(\times\) \(\dfrac{1}{2}\) = 60 (cây)

Số cây chanh là: 120 - 60 - 60 = 0 (cây)

Next week , In my free time, I love to relax myself by listening to music and watching my favorite films. I study all day, so after 7PM is the only time that I can use for myself. I have a smart phone, so I can download a lot of songs from the Internet for free, and I usually hear them with my headphone. Sometimes when my parents are not at home, I turn on the loudspeakers to have the best experience with music, but most of the time I just listen in silence. Besides music, movies are my biggest love. When I am not listening to the songs, I turn on my computer and watch some of the lasted movies on the websites. Since most of the best films are from Europe and America, this is also a way for me to improve my English skills. I usually do not use the subtitle, and I try to hear directly what the actors and actresses are saying. My parents want me to read books to even learn in my free time, but I think I should do what I actually love to make myself comfortable.

5,5 + \(\dfrac{3}{4}\) - 5 + \(\dfrac{1}{4}\)

(5,5 - 5) + (\(\dfrac{3}{4}\) + \(\dfrac{1}{4}\))

= 0,5  + 1

= 1,5 

\(\dfrac{5}{2}\) x  \(\dfrac{2}{3}\) + \(\dfrac{1}{4}\) : \(\dfrac{3}{2}\)

= \(\dfrac{5}{2}\) x \(\dfrac{2}{3}\) + \(\dfrac{1}{4}\) x \(\dfrac{2}{3}\)

=  (\(\dfrac{5}{2}\) + \(\dfrac{1}{4}\)) x \(\dfrac{2}{3}\)

= (\(\dfrac{10}{4}\) + \(\dfrac{1}{4}\)) x \(\dfrac{2}{3}\)

= \(\dfrac{11}{4}\) x \(\dfrac{2}{3}\)

= \(\dfrac{11}{6}\) 

Tính \(x\): 

  435  - [\(x\) + 16] = 425 : 17

  435 - [\(x\) + 16] = 25

          [\(x\) + 16] = 435 - 25

           \(x\) + 16 = 410

           \(x\)        = 410 - 16

          \(x\)         = 394

My house is bigger than yours.

Đề là gì ạ

Ta có:

3000+ab x 10+3=ab x 11+2970

3000+3=ab x(11-10)+2970

3003=ab+2970

=>ab=3003-2970=33

đúng tick mk nha

976 : 3 = 325.333333333

Vậy số cần điền là: 128 → 325.333333332

Trung bình cộng của dãy số chẵn liên tiếp cũng chính là trung bình cộng của số đầu và số cuối của dãy số:

            Tổng số đầu và số cuối là: 10 \(\times\) 2 = 20

            Số cuối của dãy số là: 20 - 2 = 18

            Số số hạng của dãy số đó là: ( 18 - 2): 2 + 1 = 9

            Tổng các số của dãy số đó là: 10 \(\times\) 9 = 90

            Đs...
