30% is 3/10. 260 times 3/10 is 780/10, or 78. She read 78 pages. 260 - 78 is 182 pages left.
You’d add 65+79 to get 144 then subtract that from 180 and get 36 so X would be 36 :) hope this helped!
<span>(a) the slope of curve is calculated from the derivative of the curve expression y=5/x. In this problem, the slope m=-5/(a^2).
(b) x=1, y=5，and m=-5, the tangent line is y-5=-5*(x-1).
x=4, y=5/4, and m=-5/16, the tangent line is y-5/4=-5/16*(x-4)</span>
Ans: About 2.30
-15 x 3.16 / 9 = x sqrt
-15 x 3.16 = - 47.4
-47.4 / 9 = -5.27
-5.27 sqrt = About 2.30
Hope this helped :)
