Let there be 2x science and 5x art books
<span>science books sold = 2x × 0.2 = 0.4x </span>
<span>science books unsold = 2x – 0.4x = 1.6x </span>
<span>art books sold = 5x × 0.2 = x </span>
<span>art books unsold = 5x – x = 4x </span>
<span>total books unsold = 1.6x + 4x = 5.6x </span>
<span>5.6x = 2240 </span>
<span>x = 400 </span>
<span>2x science = 800 </span>
<span>and 5x art books = 2000 </span>
Answer:-2-5÷4-1=-1
Step-by-step explanation:
W-5=5
W= 5+5 (bringing -5 to the other side, it becomes +5)
At last, W=10.
The answer is 2,100. since there are 3 feet in 1 yard, you would multiple 700 by 3.
