First, you have to follow the order of operations. (PEMDAS) So you would simplify the numbers inside of the parenthesis, (4*2), and (5-3). The equation then becomes 20 - (8) / (2). Next, you do multiplication and division next, since there is no exponent. 20 - 4. You then simplify the rest by subtracting. 20 - 4 = 16. There is your answer.
Step-by-step explanation: If the smaller number of the ratio is 24 that means the 1 is multiplied by 24 to reach the smaller share of 24. We then multiply 24 with 4 to get the number 96. Lastly you add 96 with 24 to get the total number of marbles
The relationship between x and y is a difference of 3 each time either side goes up, and that is linear. If it was exponential it would go up in a different number each time.
