The pet store has 12 reptiles.
5/12 reptiles are turtles, so 5 reptiles are turtles
2/12 reptiles are snakes, so 2 reptiles are snakes
5 plus 2 is 7
12 minus 7 is 5
there are 5 lizards
5/12 of the reptiles are lizards

Step-by-step explanation:
123.00-55=68.00
68.00 divided by 8.50= c
c = 8
68.00 divided by 8.50=8
Answer:
One way to factor equation is to find the zeros. Its obvious that x=-1 is solution for this. So one factor is (x+1)
the next factor should include 2x at first (because we have 2x^2 in the equation which can not be made any other way)
Let's suppose the factor is (x+1)(2x+b)
Since we do not know what is b open the brackets 2x^2+bx+2x+b. If this is equal to 2x^2+5x+3 then b=3. We are left with (x+1)(2x+3)=2(x+1)(x+3/2)
Would go for other shorter solutions, but they require some deeper understanding like Horner's scheme,Fermat's Theorem or even deeper which I assume You will not understand)
Sevenhundred and eighty thousand
Answer:
Multiply 20 by 14.5 and you get the total number of cash, and when the two people enter, add 4 and 5 to that total number, giving you a new total, then divide that new total by 22 because there are now 22 people in the room.
