    answer:

    4000 is the original price

    step-by-step explanation:

    c=cost

    b=base

    r=rate %

    p=percentage

    im using the formula

    c=b-p

    derive the formula p=br

    c=b-br

    10% is the last done, so where doing it first

    3060=b-b10%

    rearrange

    3060=b-0.1b

    (10%=0.1)

    3060=0.9b

    divide .9

    3,400=b

    or

    b= 3,400

    next at 15%

    3,400=b-.15b

    3,400=0.85b

    divide by 0.85

    b=4000

    1  add the whole numbers first
    6+\frac{5}{76}+\frac{7}{8}6+​76​​5​​+​8​​7​​
    2  find the least common denominator (lcd) of  \frac{5}{76}, \frac{7}{8}​76​​5​​,​8​​7​​lcd =  1523  make the denominators the same as the lcd
    6+\frac{5\times 2}{76\times 2}+\frac{7\times 19}{8\times 19}6+​76×2​​5×2​​+​8×19​​7×19​​
    4  simplify. denominators are now the same
    6+\frac{10}{152}+\frac{133}{152}6+​152​​10​​+​152​​133​​
    5  join the denominators
    6+\frac{10+133}{152}6+​152​​10+133​​
    6  simplify
    6\frac{143}{152}6​152​​143​​

    done: )

    Aahh, k, dali lng, here. pag may nakita kang dalawand term na magkaparehas and variable at ipagsama mo, tapos itranspose/ bliktarin mo ung sign ng coefficient/ number na walang 4x+7=3, ung 7 magiging -7 at ganito na ung 4x=3-7, tapos maiwan si x, kaya divide bothe sides by so x= -1
Connaissez-vous la bonne réponse?
