14x45=630
43×2=86
(14×45)-(43×2)= 630-86=544
there would be 544 pens left
Answer:
37
Step-by-step explanation:
we would had to call the number needed a random value or call it x but
let's do the calculation backward to ease things up
(566 - 11) ÷15 ➡ 555 ÷ 15 = 37
The expression can be simplified as:
k^3(k7/5)^-5
= k^(3+-5) * (7/5)^-5
(Collecting the powers of k at one side and the constants at other side)
= k^-2 * (5/7)^5
(Solving thr integer powers)
= k^-2 * (3125/16807)
63.8% to a fraction is 319/500
