Ok, so since she spent $15 each week for 10 weeks, she spent a total of $150 over those 10 weeks. The best approach I would use for this is cross multiplication. The total percentage of Books and music would be 35% out of 100% because 10+25=35. The answer is b, 50.

Hope this helps :)

Write an expression for the perimeter of this pentagon. If the perimeter is 157 units, find x.
Nat2105 [25]

This the only option to find x since doing the other way like 3x + 2 = 3x + 2 gives it an infinite solution.

4x - 1 = 3x + 2

-3x       -3x

1x - 1 = 2

   +1    +1

1x = 3

---   ----

1       1

x = 3

Check:

4(3) - 1 = 3(3) + 2

12 - 1 = 9 + 2

11 = 11

The maximum speed of the Tupolev Tu -144 airliner is 694 m/s. What is this speed in kilometers per hour?
Svetach [21]
The answer is 2498.4km/h

The speed is 694m/s =  \frac{694m}{1s}

1 m = 0.001 km          ⇒        694 m = 694 * 0.001 km = 0.694 km
1 h = 60 min = 60 * 60 s = 3600 s 

Therefore:
\frac{694m}{1s}= \frac{3600*0.694km}{3600s} = \frac{2498.4km}{1h} =2498.4km/h
