She has 6 left.
70%= 0.7
0.7 x 20 = how many she has sold (14)
OR
30%=0.3
0.3 x 20= how many she hasn't sold (6)
Tbh i dont really remember how to this this but the only way i could think of solving it is saying how a spuare/rectangle have all equal sides so if they have all equal sides you can divide that number by 4 so 4/30=7.5 so i would say x = 7.5 tell me if its wrong
~ Good Luck :D ~
Count the negative signs, if you get an odd number of negative signs, the product is a negative. If you get an even number of negative signs, the product is a positive.
in this case, there are two negatives, the the product is a positive number
Solution:
Given expression is 
.
To simplify the expression 
Let us first convert the mixed fraction into improper fraction.
Take LCM for the denominators (LCM of 4, 8 = 8) and make the same.
Now, divide 51 by 8 and again write it in the mixed fraction.
Hence, the simplified answer is 
.
Y - 9 = -1/4 ( x + 2)
answer
