2x+5 would be the equation
x is the "number" that is unknown, it's what's called a variable. Because you need two times a number(x) you put a coefficient of 2 in front of it, then simply add 5.
Examples with known variable values:
2(4)+5=13
2(2)+5=9
Answer:
48/100
Step-by-step explanation:
2/10 equals 20/100=Tommy
28/100=Billy

It appears the question is partially missing
Hello, and thanks for posting your question!
A function would be a set of ordered pairs that have no repeating "x" values, look at the example below. (V)
{(1, 0), (2, 0), (3, 0)} = Function
{(1, 0), (1, 0), (2, 0)} = Not a function.
According to this information, your answer is C. Both Set A and Set B.
Hope this helps! ☺♥
Well 9x40 would be the solution, so what is 9x40? That will be your answer.
