Basic Simplification Quiz Set 019

We have by bodmas 172 + 153 - 1 × 1185 ÷ 395 = 172 + 153 - (1 × (1185 ÷ 395)) = (172 + 153) - (1 × (3)) = (172 + 153) - 3 = 325 - 3 = 322.

The minimum value of |2x - 6| is 0. So 2x - 6 = 0, when x = 3.

Let there be N coins of each denomination. Then N × (1 + 5 + 10) = 416, which gives N = $416/16$, and 3N = 3 × $416/16$ = 78.

The maximum occurs when the value of |x - 7| is the lowest, which is 0, so the maximum value is 63.

This is a multiplication by a power of 5. The best way is to observe that 25 = 5². There are 2 powers of 5. So append 2 zeroes and divide by 2², like this: $46900/4$ = 11725.
