The Relationship Between Two Variables
Patterning and Algebra, and more...
 
1. EASY

If \(a=2b\), how many times as large as \(a\) is \(b\)?

 
2. EASY

If \(q = 847\) and \(q=r+4\) what is the value of \(r\)?

 
3. MEDIUM

\(j = (k-2) \div 3\)
If \(k=89\), what is the value of \(j\)?

 
4. MEDIUM

If \(y=4x\), when is \(x\) greater than \(y\)?

  1. Always
  2. Never
  3. Only when \(x\) is greater than 0
  4. Only when \(x\) is less than 0
  5. None of the above
 
5. HARD

When \(m=7\), \(t=26\) and when \(m=12\), \(t=41\). What could the relation be between these two variables?

  1. \(t=m\times 4 - 2\)
  2. \(t=m\times 5 - 9\)
  3. \(t=m\times 2 + 12\)
  4. \(t=m\times 3 + 5\)
  5. None of the above
