Use the rule to complete the table of values:
"The starting number is doubled, then $4$4 is subtracted."
Starting Number ($N$N) | $12$12 | $13$13 | $14$14 | $15$15 |
Answer ($A$A) | $\editable{}$ | $\editable{}$ | $\editable{}$ | $\editable{}$ |
Which of these equations describes the rule above?
$A=2\times\left(N-4\right)$A=2×(N−4)
$A=N\times2-4$A=N×2−4
$A=N^2-4$A=N2−4
$A=2+N-4$A=2+N−4
Use the rule to complete the table of values:
"The starting number has $9$9 added to it. The sum is then multiplied by $5$5."
