Answer:

$1) - 2n + 14$

$2)- 5n + 30$

Step-by-step explanation:

$n = a + (n - 1) \times d \\ = 12 + (n - 1) \times - 2 \\ = 12 - 2n + 2 \\ = - 2n + 14$

$n = a + (n - 1) \times d \\ = 25 + (n - 1) \times - 5 \\ = 25 - 5n + 5 \\ = - 5n + 30$

Explain why the numerical expression 4 less than 20 is written as 20-4 and not 4-20

Phantasy [73]

When converting English phrases into mathematical expressions/equations, we do things from left to right. That is why it's 4 - 20 instead of 20 - 4.

This rule is applied to division as well.
