He had 40 pencils left after he gave away 8, so originally he had 40 + 8 pencils, which is 48.
Now, he bought 4 packages, which had a total of 48 pencils, so divide 48 by 4, which is 12. He had 12 pencils in each package.
To determine the solution arithmetically, first add 8 to 40, then divide 48 by 4.
To determine the solution algebraically, set up and solve the equation 40 = 4x - 8.
Each package contained 12 pencils.
Hope this helps

Area of the poster board that she has left=Area of ||gm- area of ∆
Area of the poster board that she has left= 10*20-1/2*9*10
Area of the poster board that she has left=200-45=155in^2
The swimming pool is a <span>rectangular prism</span> (which means it's a 3D rectangle). To find the volume of a rectangular prism you multiply Length x Width x Height.
In this case that would mean 16*10*8 (height and depth are the same in this problem).
16*10*8=<span>1280 ft</span>³<span>
</span>
