Haala buys 13 identical shirts and 22 identical ties for £363.01
The cost of a shirt is £15.35
Find the cost of a tie.

  £7.43

Step-by-step explanation:

The total cost is ...

  13s +22t = 363.01

  13(15.35) +22t = 363.01 . . . . fill in the cost of a shirt

  22t = 163.46 . . . . . . . . . . . . . subtract 199.55

  t = 7.43 . . . . . . . . . . . divide by 22

The cost of a tie is £7.43.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
