Answer: s(s+4)=7, 7 shelves

Step-by-step explanation:

I think it's easiest to find these type of answers by finding the common factors of a number. First 77, they are 1×77 & 7×11.so you can have 11 rocks on 7 shelves or 7 rocks on 11 shelves. The question states the number or rocks on the shelf is more than the number of shelves, so you must have 11 rocks on 7 shelves. You know you have 77 rocks, so the equation must equal 77. I plugged 7 in for s in the equations to determine the correct answer. 7(7+4)=77.

belka [17]
11 as many fiction books as non fiction.

Fiction books F,  Non Fiction NF

F: NF =  11 : 1

Total ratio 11+ 1 = 12.

Fraction of Fiction books F,  =  11/12

Total books = 312.

Fiction books  =     11/12 * 312 =  286

Fiction books = 286
