Answer:
D
Step-by-step explanation:
an = 7 - 3(n - 1)
= 7 -3n - 1 *(-3)
= 7 - 3n + 3 {Combine like terms}
= 7 + 3 - 3n
= 10 - 3n
= -3n + 10

Answer:
Explanation:
Translate every verbal statement into an algebraic statement,
<u>1. Keith has $500 in a savings account at the beginning of the summer.</u>
<u>2. He wants to have at least $200 in the account by the end of summer. </u>
<u />
<u>3. He withdraws $25 a week for his cell phone bill.</u>
<u />
- Call w the number of weeks
<u>4. Write an inequality that represents Keith's situation.</u>
- Create your model: Final amount = Initial amount - withdrawals ≥ 500
With that inequality you can calculate how many week will pass before his account has less than the amount he wants to have in the account by the end of summer:
That represents that he can afford spending $ 25 a week during 12 weeks to have at least $ 200 in the account.
Solve this as you would an equation. Subtract 5x from both sides and subtract 7 from both sides and what you get is
. Solve that for x and get that
which of course means that
which is D in your choices.
