The number of permutations of 8 people taken 6 at a time is given by:
Answer:
Arithmetic.
Step-by-step explanation:
Geometric sequences have common ratios. Arithmetic sequences have common differences.

we know that, the mixture amount is the sum of 11 + p, or
11 + p = m.
we also know that, the total value is also a sum of
25.3 + 4.5p = 3.29m.
Answer:
<h2>6÷4(7+8) </h2><h2>= 22,5</h2>
<h2>8-6(4+9)</h2><h2>= 26</h2>
<h2>4÷8(9+3)</h2><h2>= 6</h2>
Step-by-step explanation:
<h2>6÷4(7+8)</h2><h3>= 6÷4(15)</h3><h3>= 1,5 × 15</h3><h3>= 22,5</h3>
<h2>8-6(4+9)</h2><h3>= 8-6(13)</h3><h3>= 2 × 13</h3><h3>= 26 </h3>
<h2>4÷8(9+3)</h2><h3>= 4÷8(12)</h3><h3>= 0,5 × 12</h3><h3>= 6</h3>
