Answer:
"The sum of two rational numbers is rational."
By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
Answer:

Equation 21.50 = 2.50x + 4
Step-by-step explanation:
21.50 - 4 = 17.50
17.50/2.50 = 7
21.50 = 2.50x + 4
x is the amount of rides

The equation is a third-degree polynomial. The only way to know its trend is to graph it. 'F(x)' means a function of x. This could be any variable (suppose it's y). Assign values for x, you get their corresponding values of y, then plot x against y. The graph is shown in the picture. As you can observe, the answer should be letter D.
Answer: 20/12
Step-by-step explanation: In order to get a 12 in the denominator
of 5/3, we multiply top and bottom of 5/3 by 4 to get 20/12.
So 20/12 is an equivalent fraction.
