Of the total number of pages in a book, 62% have pictures and the rest have no pictures. there are 310 pages with pictures in the book. what is the total number of pages in the book?

I'm pretty sure that you need to use proportions, its simple. First, place 310 over x like a fraction. then, write an equal sign and write 62% over 100 because percentage always goes on the top of 100`s. next, on the bottom write 62x over 62 and an = sign 310,000 over 62 since you multiplied 310 with 100. for example, its cross multiply. 62 goes with x and you multiply 310 with 100. so 310,000 divided by 62 = 500 pages in total.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
