Answer:
variable
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Step-by-step explanation:
What is the union of the two sets A={2,3,6,11,16} and B={6,11}? A. {2,3,6,11,16} B. {2,3,16} C. {6,11} D. {16}
Katarina [22]
Union is everything in the two sets together, so the union would be:
{2,3,6,11,16} (B is a subset of A so there is no difference)
The answer is A.

Step-by-step explanation:
Answer:
a) 9r=63
b) 14 mi/h
Step-by-step explanation:
Let say r the speed of the slower cyclist,
2*r the speed of the faster cyclist,
they meet 3 hours later:
a)
<u> (r+2*r)*3=63 </u>
3r*3=63
9r=63
r= 63/9
r=7 (mi/h)
b)
<u>2r=14 (mi/h)</u>
